Write an algorithm for a vending machine that sells just one product. The machine flashes a yellow light when the quantity inside is below 40% of capacity
Answer:
The algorithm is as follows:
1. Start
2. Capacity = 100%
3. Input Status (True/False)
4. While Status == True
4.1. Read Quantity (%)
4.2. Capacity = Capacity - Quantity
4.3. If Capacity < 40%
4.3.1 Display Yellow Flash
4.4. Input Status (True/False)
5. Stop
Explanation:
This starts the algorithm
1. Start
The capacity of the machine is initialized to 100%
2. Capacity = 100%
This gets the status of the sales
3. Input Status (True/False)
The following iteration is repeated until the status is false
4. While Status == True
Read current sales quantity from the user
4.1. Read Quantity (%)
Remove the quantity from the capacity
4.2. Capacity = Capacity - Quantity
Check is capacity is below 40%
4.3. If Capacity < 40%
If yes, display yellow flashes
4.3.1 Display Yellow Flash
This gets the status of the sales
4.4. Input Status (True/False)
End algorithm

Please select an option:
Then, if the user selects:
-P (lowercase or uppercase): the program displays the array elements position and
value pairs for all member elements of the array.
-R (lowercase or uppercase): the program displays the reversed version of the
array
-A (lowercase or uppercase): the program calculates and displays the average of the
array elements
-S (lowercase or uppercase ): the program asks the user to insert an integer number
and look for it in the array, returning the message wheher the number is found and
its position ( including multiple occurences), or is not found.
-Q (lowercase or uppercase): the program quits.
NOTE: Until the last option (‘q’ or ‘Q’) is selected, the main program comes back at

Write a program palindrome.py that prompts for a sequence of words or numbers on a single line and checks if the entries are palindromes or not. A word or a number is a palindrome if it remains unchanged when reversed. e.g. rotor is a palindrome; but python is not a palindrome. e.g. 737 is a palindrome; but 110 is not a palindrome. The program receives the sequence as input and returns True if an entry is a palindrome or False if an entry is not a palindrome. Print the boolean value on one line. Print the palindromes count on the next line.
Answer:
Explanation:
The program first asks the user for the sequence of words. Then it splits the sequence into an array of words. Then it loops through the array checking each word to see if it is a palindrome. If it is it prints the word, the boolean value, and adds 1 to the palindrome_count variable. Otherwise it prints the word, false, and moves on to the next word in the list. Finally, it prints out the total value of palindrome_count.
word = input("Enter sequence of words: ")
word_list = word.split(' ')
print(word_list)
palindrome_count = 0
for word in word_list:
print('\n\n')
reverse = word[::-1]
if word == reverse:
print(word, end='\n')
print(True, end="\n")
palindrome_count += 1
else:
print(word, end='\n')
print(False, end='\n')
print("\n\nNumber of Palindromes in Sequence: " + str(palindrome_count))

2.13 LAB: Branches: Leap Year
A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the
difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The
requirements for a given year to be a leap year are:
1) The year must be divisible by 4
2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400
Some example leap years are 1600, 1712 and 2016.
Write a program that takes in a year and determines whether that year is a leap year.
Ex If the input is
1712
the output is
1712 13 leap year.
Ex If the nouts
1913
the outoutis
1913 not leap year.
Written is Coral Language
Answer:
integer userInput
userInput = Get next input
if userInput % 400 == 0
Put userInput to output
Put " is a leap year" to output
else
if userInput % 4 == 0
Put userInput to output
Put " is a leap year" to output
else
Put userInput to output
Put " is not a leap year" to output
Explanation:
I don't know what is so special about Coral but here we go. I couldn't find and IDE that supported Coral so I just used their Coral simulator on their website. The first if statement on line 5 determines if the number is divisible by 400. If so, the leap year is on a century year e.g 1900 1800. If not, the else statement will be executed and the second if statement will execute. If the number is divisible by 4, it is a leap year. If not, the else statement gets executed in which case the number was not a century leap year or a leap year. After that the program terminates.
Hope this helped :) If it didn't let me know and I do my best to find out what went wrong.

Write a game that performs the roll of two dice randomly. The game should first ask for a target sum. Everytime the player enters r, the program should repeatedly print the side of the dice on a separate line. The game should stop prompting if one of these two events occur: -The sum of the two sides is equal to the target sum. -The player enters q.
Answer:
Explanation:
The following program was written in Java. It asks the user to first enter the target sum. Then it creates a while loop that continues asking the user to either roll dice or quit. If they decide to roll, it rolls the dice and prints out both values. If the target sum was hit, it prints that out and exits the program otherwise it loops again. The code has been tested and can be seen in the attached image below.
import java.util.Random;
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Random rand = new Random();
Scanner in = new Scanner(System.in);
System.out.print("Enter Target Sum: ");
int targetSum = in.nextInt();
while (true) {
System.out.println("r: Roll Again");
System.out.println("q: Quit");
String choice = in.next();
char choiceModified = choice.toLowerCase().charAt(0);
if (choiceModified == 'r') {
int roll1 = rand.nextInt(6) + 1;
int roll2 = rand.nextInt(6) + 1;
int total = roll1 + roll2;
System.out.println("Dice 1: " + roll1);
System.out.println("Dice 2: " + roll2);
if (total == targetSum) {
System.out.println("Target Sum of " + targetSum + " hit.");
break;
}
} else if (choiceModified =='q') {
break;
} else {
System.out.println("Wrong choice");

why SSTF disk scheduling is not practically feasible?
Answer:
There is a lack of predictability because of the high variance of response time. Additionally, SSTF may cause starvation of some requests. Starvation is possible for some requests as it favors easy to reach requests and ignores the far-away processes.
SSTF disk scheduling is not practically feasible because it makes an external call and is forced to wait for I/O to complete, thereby giving up its first-place position.
What is SSTF disk scheduling?Shortest Seek Time First (SSTF) is a disc scheduling algorithm that is abbreviated as SSTF. Before moving the head away to service other requests, it selects the request that is closest to the current head location.
Because of the high variance in response time, there is a lack of predictability. Furthermore, SSTF may cause some requests to be denied. Some requests may experience starvation because the system prioritizes nearby requests and overlooks distant operations.
Therefore, because it makes an external call and is obliged to wait for I/O to complete, SSTF disc scheduling is not viable because it loses its first-place status.

While troubleshooting an Internet connection problem for your network, you restarted the modem and then the router. The router is now communicating with the Internet, which you can confirm by observing the blinking light on the router's WAN indicator. However, now your laptop is not communicating with the router. Order the commands below to fix the problem and confirm connectivity.
a. ping
b. ipconfig /renew
c. nslookup microsoft.com
d. ipconfig /release
Answer:
d. ipconfig /release
b. ipconfig /renew
a. ping
c. nslookup microsoft.com
Explanation:
A router can be defined as a network device that is designed typically for forwarding data packets between two or more networks based on a well-defined routing protocol.
Basically, it is an electrical device or node that is designed to connect two (2) different networks (in different locations) together and allows them to communicate.
Generally, routers are configured using a standard routing protocol with an IP address as the default gateway.
Dynamic Host Configuration Protocol (DHCP) is a standard protocol that assigns IP address to users automatically from the DHCP server.
Basically, a DHCP server is designed to automatically assign internet protocol (IP) address to network devices connected to its network using a preconfigured DHCP pool and port number 67.
On a related note, when a computer that is configured with DHCP cannot communicate or obtain an IP address from the DHCP server, the Windows operating system (OS) of the computer automatically assigns an IP address of 169.254.33.16, which typically limits the computer to only communicate within its network.

Shawn's supervisor has tasked him with determining how the company can increase the security of its Wi-Fi. Shawn plans to present several options to his supervisor and ask her to check his work. Which of the following is not a strong security method? (Select TWO.)
a. Disabling SSID
b. WPS
c. MAC filtering
d. Setting encryption
Answer:
The not strong security methods are:
a. Disabling SSID
b. WPS
Explanation:
When you disable SSID, you only make your Wi-Fi secure for the less determined attackers. By disabling the SSID (network name), those who are less technically inclined are prevented from connecting to the network but, this will not deter a more determined and technically savvy adversary. The best two options are MAC filtering and setting encryption. WPS (Wi-Fi Protected Setup) enables the process of connecting to a secure wireless network from a computer or other device easier instead of making it harder.
you are the network administrator for a college. wireless access is widely used at the college. you want the most secure wireless connections you can have. which of the following would you use?
A WPA
B WEP2
CWEP
D WPA2
Answer:
D. WPA2
Explanation:
Required
Of the 4 options, which is the most secured?
WPA was created as a solution to the vulnerabilities in WEP/WEP2. Then, WPA was upgraded to WPA2.
WPA2 is the least vulnerable to hacks because for every user that is connected to the network through WPA2, a unique encryption is made available for such connection.
Hence, the most secure connection, of the 4 is WPA2.
Kamal plans to offer new, more favorable contracts to business customers who are now receiving a discount and use wireless services. Determine whether each customer should receive a new contract as follows:
a. In cell 15, enter a formula using the AND function that tests whether the Wireless value is equal to "Y" and whether the Discount value is equal to "Y".
b. Fill the range 16:118 with the formula in cell 15.
Solution :
'AND" operation is a logical operation and is used in logical connective combining two statements and in truth tables.
Using AND operation verifies whether the outcome P and Q is true only when both the P as well as Q are true. If one of the P or Q is not true, then outcome result will be false.
In the context, Kamal wishes to offer a new and more favorable contracts to the business customers who use a wireless services and receive a discount.
Therefore, using the AND operation of the customers as :
Customer Wireless Discount Outcome
A N N FALSE
B Y N FALSE
C N Y FALSE
D Y Y TRUE
If you were driving the blue Prius in the situation pictured above, explain why the red Mustang should be given right-of-way at this intersection.
Answer:
The red Mustang should be given the right-of-way at this intersection because:
The red Mustang arrived first before the blue Prius and is closer to the stop sign before the arrival of the blue Prius. This implies that the red Mustang must have waited for its turn, unlike the blue Prius that just arrived at the intersection.
Explanation:
Traffic laws, regulations, and IPDE defensive driving strategy require that drivers always give way to the vehicle that arrived before them at an intersection. Assuming that multiple vehicles reach the intersection simultaneously, then the vehicle must be given the right-of-way. Alternatively, the traffic lights at the intersection should be obeyed and be allowed to regulate the movement of vehicles. IPDE defensive driving strategy requires drivers to be watchful of their driving spaces to determine the appropriate time to move.

Use the tables below to show the difference between the results of a natural join, an equijoin (with PROF_CODE = 2) and a full outer join. Provide the resulting table of each join
Answer:
Code:
CREATE TABLE student (
stu_code INTEGER PRIMARY KEY,
prof_code INTEGER
);
INSERT INTO student VALUES (100278,null);
INSERT INTO student VALUES (128569,2);
INSERT INTO student VALUES (512272,4);
INSERT INTO student VALUES (531235,2);
INSERT INTO student VALUES (531268,null);
INSERT INTO student VALUES (553427,1);
CREATE TABLE professor (
prof_code INTEGER PRIMARY KEY,
dept_code INTEGER
);
INSERT INTO professor VALUES (1,2);
INSERT INTO professor VALUES (2,6);
INSERT INTO professor VALUES (3,6);
INSERT INTO professor VALUES (4,4);
The SQL NATURAL JOIN is a type of EQUI JOIN and is structured in such a way that, columns with the same name of associated tables will appear once only. In our Example, Prof_code will appear only once and it will be matched in both the table;
SELECT * FROM Student natural join Professor on student.prof_code=Professor.prof_code ;
Stud_code Prof_code Dept_code
128569 2 6
512272 4 4
531235 2 6
553427 1 2
EQUI JOIN performs a JOIN against equality or matching column(s) values of the associated tables and an equal sign (=) is used as a comparison operator in the where clause to refer to equality. In our example, it will only show the result with prof_code=2 from the natural join result.
SELECT * FROM Student join Professor on student.prof_code=Professor.prof_code where student.prof_code=2;
Stud_code Prof_code Prof_code Dept_code
128569 2 2 6
531235 2 2 6
In SQL the FULL OUTER JOIN combines the results of both left and right outer joins and returns all (matched or unmatched) rows from the tables on both sides of the join clause.
SELECT * FROM professor full outer join student on professor.prof_code=student.prof_code ;
Stud_code Prof_code Prof_code Dept_code
100278
128569 2 2 6
512272 4 4 4
531235 2 2 6
