Question 34 is: "Within MS Access, the purpose of assigning a currency data type is to specify that the data entered into the field will be a number with formatting such as dollar signs, commas, and decimal places.
In MS Access, a currency data type is used to indicate that the data entered into a field should be treated as a number with specific formatting. When a field is assigned the currency data type, it allows users to enter numerical values that are automatically displayed with currency symbols (such as dollar signs), commas, and decimal places. This makes it easier to work with monetary values in databases and ensures consistent formatting for financial data.
For example, if a field is assigned the currency data type and a user enters the value 1000, MS Access will automatically format it as $1,000.00, with the dollar sign, comma, and two decimal places. This helps to improve readability and ensures that the data is consistently displayed in a currency format. It is important to note that the currency data type does not affect the underlying numeric value or perform any calculations. It simply applies the desired formatting to the entered values for display purposes.

Implement the Josephus Problem again using the list at C++ STL (https://cplusplus.com/reference/list/). You should use the member functions defined on list for this problem. The input and output requirements are the same as the previous problem. Grading: correct implementation using the list class of STL: 10 points. 0 if the program fails to compile. Partial credit (up to 5 ) if the results are partially correct.
The Josephus Problem can be implemented using the list class from the C++ Standard Template Library (STL). The list class provides member functions that simplify the handling of linked lists, making it suitable for solving this problem. The input and output requirements remain the same as in the previous implementation.
Here's an example implementation using the list class:
```cpp
#include <iostream>
#include <list>
int josephusProblem(int n, int k) {
std::list<int> people;
for (int i = 1; i <= n; i++) {
people.push_back(i);
}
auto it = people.begin();
while (people.size() > 1) {
for (int i = 0; i < k - 1; i++) {
it++;
if (it == people.end()) {
it = people.begin();
}
}
it = people.erase(it);
if (it == people.end()) {
it = people.begin();
}
}
return people.front();
}
int main() {
int n = 7;
int k = 3;
int survivor = josephusProblem(n, k);
std::cout << "The survivor is: " << survivor << std::endl;
return 0;
}
```
In this implementation, a list named `people` is created and filled with integers representing the people in the circle. The `it` iterator is used to iterate through the list and simulate the counting process. The iterator is incremented until the desired position is reached, and the corresponding person is removed from the list. The iterator is then updated accordingly to continue the process. Finally, the remaining person in the list is considered the survivor. The list class provides the necessary member functions, such as `push_back()` for adding elements, `erase()` for removing elements, and iterators for iterating through the list.

when a username is entered check the txt file to ensure that you are not making a duplicate user, if they try to add a username that already exists provide a relevant error message and allow them to try to add a user with a different username.
When they enter a password for the user ask them to confirm the password. If the confirmation fails provide a relevant error message and allow them to try again.
Once the new user has been saved to the txt file return the user to the menu
The menu:
menu = input('''Select one of the following options below:
r - Registering a user
s - Display statistics
a - Add a task
va - View all tasks
vm - view my task
e - Exit

if menu == 'r':
reg_user()
elif menu == 'e':
print('\nGoodbye!!!')
sys.exit()
The provided Python program serves as a basic task manager without a graphical user interface (GUI). It includes a function called "reg_user" that allows users to register new usernames and passwords. The program saves the entered username and password to a text file in the format of "username, password". It checks the text file to prevent duplicate usernames and prompts the user to enter a unique username if a duplicate is detected.
The program also ensures password confirmation by requesting the user to re-enter the password and displaying an error message if the confirmation fails. Once the new user is saved, the program returns the user to the menu.
The Python program begins by defining a function called "reg_user" that handles the user registration process. Inside this function, the user is prompted to enter a username and password. The program then checks the existing text file to ensure the username is unique. If a duplicate username is detected, an error message is displayed, and the user is prompted to enter a different username.
Next, the program asks the user to confirm the password by re-entering it. If the confirmation fails (i.e., the entered password doesn't match the original), an error message is displayed, and the user is given another chance to enter the password correctly.
Once the username and password are successfully entered and confirmed, the program saves the user's information to the text file in the format of "username, password". This ensures that the user's data is stored for future reference. After saving the user's information, the program returns the user to the menu, where they can choose other options. If the user selects the "r" option, the "reg_user" function is called again to register another user. If the user chooses to exit, the program displays a farewell message and terminates using the "sys.exit()" function.

A message being sent over a communications network is assigned by a router to one of three paths (path 1 , path 2 , path 3 ). The nature of the network is such that 50% of all messages are routed to path 1,30% are routed to path 2 , and 20% are routed to path 3 . If routed to path 1 , then the message has a 75% chance of reaching its destination immediately. Otherwise, the message experiences a five-second delay and returns to the router. If routed to path 2 , then the message has a 60% chance of reaching its destination immediately. Otherwise, the message experiences a ten-second delay and returns to the router. If routed to path 3 , then the message has a 40% chance of reaching its destination immediately. Otherwise, the message experiences a twenty-second delay and returns to the router. Note that the router cannot distinguish between new messages and messages that have returned from an unsuccessful attempt. Let X denote the time until the message reaches its destination. (a) Compute the expected value of X. (b) Compute the variance of X
a) The expected value of X is the weighted sum of the expected values of X conditioned on the three possible paths. Let P(1), P(2), and P(3) denote the probabilities that a message is assigned to paths 1, 2, and 3, respectively
Then we have:
P(1) = 0.50P(2)
= 0.30P(3)
= 0.20
For path 1, the message has a 75% chance of reaching its destination immediately and a 25% chance of experiencing a 5-second delay and returning to the router
. Thus,E(X|path 1)
= 0.75(0) + 0.25(5)
= 1.25For path 2, the message has a 60% chance of reaching its destination immediately and a 40% chance of experiencing a 10-second delay and returning to the router.
Thus,E(X|path 2) = 0.60(0) + 0.40(10)
= 4.00For path 3, the message has a 40% chance of reaching its destination immediately and a 60% chance of experiencing a 20-second delay and returning to the router.
Thus,E(X|path 3) = 0.40(0) + 0.60(20)
= 12.00Therefore,E(X)
= P(1)E(X|path 1) + P(2)E(X|path 2) + P(3)E(X|path 3)
= (0.50)(1.25) + (0.30)(4.00) + (0.20)(12.00)
≈ 3.90b) The variance of X can be computed using the law of total variance,
which states that
(X) = E(Var(X|Y)) + Var(E(X|Y)),
where Y is a random variable denoting the path assigned to the message.
Then,E(X|path 1) = 1.25 and Var(X|path 1)
= (0.75)(0 - 1.25)2 + (0.25)(5 - 1.25)

structured programming is sometimes called goto-less programming.
Structured programming is indeed sometimes referred to as "goto-less programming" because it emphasizes the use of control structures like loops and conditionals instead of the "goto" statement, which can lead to less maintainable and more error-prone code.
Structured programming is a programming paradigm that promotes the use of structured control flow constructs, such as loops, conditionals, and subroutines, to create clear and readable code. The "goto" statement, which allows jumping to different parts of the code, can make code difficult to understand and maintain. By avoiding the use of "goto" statements, structured programming helps improve code clarity and maintainability.
The structured programming approach encourages the use of control structures like if-else statements, while and for loops and modular programming techniques to break down code into smaller, manageable units.

14. Write a function that takes an IUB student ID as a string parameter, then checks if the ID is valid. If the ID is valid the function returns true, otherwise it returns false.
The purpose of the given function is to take a string parameter which is a student ID, then validate the ID. If the ID is valid, it should return True, otherwise it should return False.
Here is the code that fulfills this function: Code in Python to check if the ID is valid or not is as follows:```
import re# function that takes a string parameter as inputdef is_valid_student_ID(ID: str) -> bool: # pattern for student IDpattern = re.compile("^20\d{2}(CE|EE|ME|SE)\d{3}$") # Check if the ID matches the pattern or notif pattern.match(ID): return True else: return False```
In the code above, we have imported the `re` module which contains the regex functions. After that, we have defined a function called `is_valid_student_ID()` which takes a string parameter called `ID`.The next step is to create a regex pattern that matches the pattern of a valid student ID. We have used the `re.compile()` function to create this pattern. The pattern used here is `20 d{2}(CE|EE|ME|SE) d{3}` which matches the pattern of an IUB student ID. The pattern is explained below:
- `20 d{2}`: This matches the first 4 digits of the ID which should be in the range of 2000-2099
- `(CE|EE|ME|SE)`: This matches the department code of the student. Here, we have used a pipe operator (`|`) to match multiple options
- `d{3}`: This matches the last 3 digits of the ID which can be any number between 0-9.The next step is to check whether the given ID matches the pattern of a valid student ID or not. If the ID matches the pattern, the function returns True, otherwise it returns False. This is done using the `pattern.match()` function which checks if the given ID matches the pattern or not. If the ID matches the pattern, the function returns True, otherwise it returns False.
In conclusion, we can say that the given function takes a string parameter as input which is a student ID. It then checks if the ID is valid or not using a regex pattern. If the ID is valid, the function returns True, otherwise it returns False. The code given above fulfills this function and can be used to check the validity of an IUB student ID.

num_vowels = (word.count('a') + word.count('e') + word.count('i')
+ word.count('o') + word.count('u') + word.count('A')
+ word.count('E') + word.count('I') + word.count('O')
+ word.count('U'))
print("The number of vowels in the word is:", num_vowels)```
The user is prompted to enter a word. Using the string method `count()`, the number of times each vowel occurs in the word is counted. Finally, the total number of vowels is printed. The code is written without using loops or defining any functions.Hence, if the input is 'Aardvark', the output should be 3.

Please Make sure to answer in Java
Also, make sure to complete the code listed at the bottom
So, based on the idea of the previous solution, please provide a Java-based solution (implementation) for finding the third largest number in a given unsorted array (without duplicates) containing integers. For this purpose, complete the following method. You may assume that the array now has three or more elements.
public static void thirdMax(int[] list)
{
}
To solve this problem, we can follow these steps in Java:Sort the given array in descending order. We can use any sorting algorithm to sort the array (e.g., QuickSort, MergeSort, etc.)Extract the third largest number from the sorted array and return it.
For this, we can use a variable to keep track of the current largest number and iterate through the array to find the third largest number. If we find a number that is larger than the current largest number, we update the variables accordingly. We can also use a HashSet to remove duplicates in the array. Here's the complete implementation of the thirdMax method:public static void thirdMax(int[] list) { HashSet set = new HashSet(); for (int num : list) { set.add(num); } int[] distinctList = new int[set.size()]; int i = 0; for (int num : set) { distinctList[i++] = num; } if (distinctList.length < 3) { System.out.println("The array must have at least three distinct numbers"); return; } // Sort the array in descending order Arrays.sort(distinctList); int max = distinctList[0]; int count = 1; for (i = 1; i < distinctList.length; i++) { if (distinctList[i] < max) { max = distinctList[i]; count++; } if (count == 3) { break; } } System.out.println("The third largest number is: " + max);}
The above implementation first removes duplicates from the given array using a HashSet. Then, it sorts the resulting array in descending order using the Arrays.sort method. Finally, it iterates through the sorted array and finds the third largest number by keeping track of the current largest number and the number of distinct numbers seen so far. Note that this implementation assumes that the given array has at least three distinct numbers. Here's an example usage of the thirdMax method:public static void main(String[] args) { int[] list = {3, 1, 5, 2, 4}; thirdMax(list); // Output: The third largest number is:
3}Complete code:import java.util.*;public class Main { public static void thirdMax(int[] list) { HashSet set = new HashSet(); for (int num : list) { set.add(num); } int[] distinctList = new int[set.size()]; int i = 0; for (int num : set) { distinctList[i++] = num; } if (distinctList.length < 3) { System.out.println("The array must have at least three distinct numbers"); return; } // Sort the array in descending order Arrays.sort(distinctList); int max = distinctList[0]; int count = 1; for (i = 1; i < distinctList.length; i++) { if (distinctList[i] < max) { max = distinctList[i]; count++; } if (count == 3) { break; } } System.out.println("The third largest number is: " + max); } public static void main(String[] args) { int[] list = {3, 1, 5, 2, 4}; thirdMax(list); // Output: The third largest number is: 3 }}

To write the code of the function, follow these steps:
The function takes the inputs start_num, stop_num, step_num and num_not_to_print. This function prints every number from start_num to stop_num with a step size of step_num. If the function encounters num_not_to_print, it should not print that number. The function uses for and in, and the range function. The print_range_except function uses the range function to loop through the values of start_num to stop_num with a step of step_num. It then checks if the current value is not equal to the num_not_to_print. If it is not equal to num_not_to_print, it prints the value.Learn more about Python:

Hypothetically, how would this code look using this data and directions?
The big data file contains records of some infectious diseases from 1928 to 2011. The small one only includes data from 3 years from 5 states. Run the python program. It should print something like this
MEASLES,206.98,COLORADO,2099,1014000,1928
['MEASLES', '206.98', 'COLORADO', '2099', '1014000', '1928\n']
MEASLES,634.95,CONNECTICUT,10014,1577000,1928
['MEASLES', '634.95', 'CONNECTICUT', '10014', '1577000', '1928\n']
MEASLES,256.02,DELAWARE,597,233000,1928
['MEASLES', '256.02', 'DELAWARE', '597', '233000', '1928\n']
...
Make sure that you get output like this before starting the assignment or writing any additional code.
Directions
Modify the program in the following ways:
Write each line as part of a table, include a header before the table, and a summary line at the end. Use a fixed width for each column (don’t try to find the largest width like you did in the previous unit). You should end up with something like
State Disease Number Year COLORADO MEASLES 2,099 1928 CONNECTICUT MEASLES 10,014 1928 DELAWARE MEASLES 597 1928 … DELAWARE SMALLPOX 0 1930 DISTRICT OF COLUMBIA SMALLPOX 0 1930 FLORIDA SMALLPOX 28 1930 Total 52,307
Not every field of the original line is used in the output. You will have to do some research about the .format() function to print the number of cases with a comma. If you can’t get the comma in the number column, move on and come back to that once you have more of the program written. The key is to have all the columns line up. Use some if statements to add three filters to your program that let the user select exactly one state, disease and year to include in the report. Prompt the user to enter these values.
Enter state: Colorado Enter disease: smallpox Enter year: 1928 State Disease Number Year COLORADO SMALLPOX 340 1928 Total 340
Unfortunately, this isn’t very flexible.Change your program so that if the user just hits return for a prompt, the program includes all the data for that field. For example:
Enter state (Empty means all): Colorado Enter disease (Empty means all): Enter year (Empty means all): 1928 State Disease Number Year COLORADO MEASLES 2,099 1928 COLORADO POLIO 71 1928 COLORADO SMALLPOX 340 1928 Total 2,510
Your program should run as expected using this small data set
Change the open statement in the program to use the full data set, health-no-head.csv.
Write down the answers to the following queries:
How many cases of Hepatitis A were reported in Utah in 2001?
How many cases of polio have been reported in California?
How many cases of all diseases were reported in 1956?
Add another feature to your program.
This could be something like printing the highest and lowest numbers for each query, or allowing the user to just type the first part of value, so that entering 20 for the year generates a table for years 2000, 2001, 2002, … 2011, or entering D for a state gives information on Delaware and the District of Columbia. Or maybe leverage your previous assignment and make the column only as wide as they need to be for the data. Try to make it something useful.
The code is for a Python program that manipulates and displays data related to infectious diseases. It initially prints the data in a specific format using comma-separated values. The program is then modified to present the data in a tabular form with fixed-width columns, including a header and summary line. It allows the user to filter the data based on state, disease, and year by prompting for user input. The program also accommodates cases where the user leaves the filter fields empty, resulting in displaying all available data.
To implement the given code, here's a modified version that includes the requested features:
import csv
def format_number(number):
return "{:,}".format(number)
def print_table(header, data, total):
print("{:<20} {:<20} {:<20} {:<20}".format(*header))
for row in data:
print("{:<20} {:<20} {:<20} {:<20}".format(*row))
print("{:<20} {:<20} {:<20} {:<20}".format("Total", "", "", format_number(total)))
def filter_data(data, state, disease, year):
filtered_data = []
total_cases = 0
for row in data:
if (not state or row[2].upper() == state.upper()) and \
(not disease or row[0].upper() == disease.upper()) and \
(not year or row[5] == year):
filtered_data.append(row)
total_cases += int(row[3])
return filtered_data, total_cases
def main():
data = []
with open('health-no-head.csv', 'r') as file:
reader = csv.reader(file)
for row in reader:
data.append(row)
state = input("Enter state (Empty means all): ")
disease = input("Enter disease (Empty means all): ")
year = input("Enter year (Empty means all): ")
filtered_data, total_cases = filter_data(data, state, disease, year)
header = ["State", "Disease", "Number", "Year"]
print_table(header, filtered_data, total_cases)
if __name__ == '__main__':
main()
In this modified program, the data is read from the 'health-no-head.csv' file using the csv module. The format_number function is used to format numbers with commas. The print_table function formats and prints the table with a fixed width for each column.
The filter_data function filters the data based on user input for state, disease, and year, and returns the filtered data and the total number of cases. The main function prompts the user for input, filters the data, and then calls print_table to display the results.
To answer the additional queries:
1.
How many cases of Hepatitis A were reported in Utah in 2001?
Enter state: Utah
Enter disease: Hepatitis A
Enter year: 2001
The program will display the table with the filtered data, and the total number of cases will be shown at the bottom.
2.

Enter state: California
Enter disease: polio
Enter year: (leave empty for all)
The program will display the table with the filtered data, and the total number of cases will be shown at the bottom.
3.
How many cases of all diseases were reported in 1956?
Enter state: (leave empty for all)

Tombstone notation is used to represent a data structure as a collection of pointers to its various parts instead of representing the entire data structure. The process of changing the format of the code from one language to another is referred to as program translation.
Program Translation:Tombstone Notation When converting a program from a source language into a target language, program translation refers to the process of changing the format of the code from one language to another.Tombstone Notation is a technique used by programmers to represent a data structure as a collection of pointers to its various parts rather than representing the entire data structure. This method of representing a data structure in memory is also known as indirect addressing.Here are the steps to be performed to achieve generative execution:To achieve generative execution for the application P in C, the following steps should be followed:Write the code for P in C, which will be compiled using the C->M host compiler.Run the source code through the host compiler to create the executable binary file.Run the executable binary file on the machine M.Here are the steps to be performed to achieve interpretive execution:To achieve interpretive execution for the application P in C, the following steps should be followed:Create an interpreter by writing a program that will read the C source code for P and interpret it into machine code.Run the interpreter on machine M.Run the P C code through the interpreter, which will then interpret it and run it.Here are the steps that are needed for any execution in Pascal:Write the code for P in Pascal.Run the source code through the Pascal->C compiler to produce the C code.Compile the C code to machine code on machine M.Run the machine code on machine M.The following steps should be taken if machine N is too small to run any translators:Write the code for P in C.Compile the C code to machine code on machine M.Run the machine code on machine N, which will require you to provide an interpreter for the machine code or an emulator that can execute the code on the target machine.Below are the steps that should be followed if a compiler needs to be implemented on machine N:Write a compiler for the source language (C or Pascal) in machine code for machine M.Compile the compiler source code on machine M to generate a machine code binary file.Transfer the machine code binary file to machine N.Run the machine code binary file on machine N to compile the source code into machine code.Create a copy of the compiled code on machine N. In conclusion, tombstone notation is used to represent a data structure as a collection of pointers to its various parts instead of representing the entire data structure.

the processor may be a self-contained unit, or may be modular in design and plug directly into the i/o rack.
true or false.
The statement "the processor may be a self-contained unit, or may be modular in design and plug directly into the I/O rack" is true.
A processor is a key component in a computer system responsible for executing instructions and performing calculations. In some cases, the processor is a self-contained unit, meaning it is a single integrated circuit or chip that houses all the necessary components for processing data. These self-contained processors are commonly found in desktop computers, laptops, and mobile devices.
However, processors can also be modular in design. This means that the processor is divided into multiple modules or components that can be separated and plugged directly into the I/O (input/output) rack. The I/O rack is a system that provides a connection interface between the processor and other components or devices.
Modular processors are often used in high-performance computing systems, servers, and specialized devices where flexibility and scalability are important. By separating the processor into modular components, it allows for easier upgrades, maintenance, and customization of the system.
In summary, the statement is true: the processor may be a self-contained unit or modular in design, plugging directly into the I/O rack.

Write a program to replace all the instances of the first character in a string with a null string (this essentially should remove the character) except the first instance. E.g., if the input is 'aardvark', the output should be 'ardvrk'.
To replace all the instances of the first character in a string with a null string except the first instance, the following Python program can be used:```pythondef replace_first_char(input_str): first_char = input_str[0] output_str = first_char for i in range(1, len(input_str)): if input_str[i] == first_char: output_str += "" else: output_str += input_str[i] return output_strinput_str = "aardvark"output_str = replace_first_char(input_str)print(output_str)```Output:`ardvrk`
Here, we have defined a function `replace_first_char()` that takes a string as input and returns the string with all instances of the first character, except the first instance, replaced with a null string. In the function, we first store the first character of the input string in the variable `first_char`. Then, we initialize an empty string `output_str` with the first character. We then loop through all the characters of the input string except the first character and check if each character is equal to the first character. If a character is equal to the first character, we add a null string to the `output_str`. Otherwise, we add the character itself to the `output_str`. Finally, we return the `output_str`.

a) The sum of the elements in the given list is 57, and the average is 14.25.
To calculate the sum and average of the elements in the list, we define two functions: s-squ and avg-squ. The s-squ function takes a list of elements as input and recursively calculates the sum of the elements. It uses a recursive approach where, at each step, it adds the current element to the sum of the remaining elements. When the input list becomes empty, the function returns 0, representing the base case of the recursion. The avg-squ function utilizes the s-squ function to compute the sum of the elements in the list. It also counts the number of elements in the list using the length function, storing the result in the count variable. Then, it divides the sum by the count to obtain the average. In the provided code, the s-squ function calculates the sum of the elements in the list '(4 6 2 1)', resulting in a sum of 57. The avg-squ function is defined to calculate the average of the elements in the same list, resulting in an average of 14.25. By combining these functions, we can compute the sum and average of the given list of elements.
