Explanation:
Hash functions use algorithms use a big chunk of data and squeeze it into a small amount to verify something like a file or an application.
A. True
B. False
Answer:
A. True
Explanation:
Identifying and verifying files/applications is one use of hash functions.
Create a two functions: first called grocery_cost(food), where food can be one item or a list of items from the stock and price dictionaries, the second is called stock_check(stock_list) where a store manager can check if stock numbers are at a minimum value.grocery_cost: loops through the argument food, notes the price, checks the stock, calculates and prints the total cost and changes the stock number. You will need to use a for statement to loop through the items in food and an if statement to check and update the stock (substract one from the stock for each item in the stock).Stock_check: loops through each item in the stock dictionary and uses an if-statement to print a statement if stock is less than 5.Given:stock_key={'tomato soup':20,'cheese':10,'milk':25,'oreos':100,'red bull':0,'apples':17,'oranges':4}price_key={'tomato soup':1.85,'cheese':3.99,'milk':4,'oreos':7.49,'red bull':0.99,'apples':0.59,'oranges':1.29}
Answer:
stock_key={'tomato soup':20,'cheese':10,'milk':25,'oreos':100,'red bull':0,'apples':17,'oranges':4}
price_key={'tomato soup':1.85,'cheese':3.99,'milk':4,'oreos':7.49,'red bull':0.99,'apples':0.59,'oranges':1.29}
def grocery_cost(*args):
total_cost = 0
for arg in args:
if arg in stock_key.keys():
stock_key[arg] -= 1
total_cost += price_key[arg]
print( f"Total cost of groceries: {total_cost}")
def stock_check():
for key, value in stock_key.items():
if value < 5:
print(f"The stock \"{key}\" is less than 5.")
grocery_cost('apples', 'oranges','milk', 'oreos','cheese')
stock_check()
Explanation:
The functions of grocery_cost and stock_check are python defined functions. The former accepts a list of one or more items and calculates the total cost of the grocery items from the stock and price dictionary while the latter check the size of the stock in the food store.
What is the output of the following program?
numA = 2
while numA < 30:
numA = numA * 5
print(numA)
Answer:
the output of that code would be invalid syntax since the line,
>>> numA = numA * 5
is not indented.
The output of
>>> numA = 2
>>> while numA < 30:
>>> numA = numA * 5
>>> print(numA)
would be 50.
The output of the following program is 10. This is because it is represented in the program that the value of numA would be less than 30.
What is the significance of the output of the program?The significance of the output of the program is understood by the fact that it delivers some values or concepts to the user with respect to the instruction he/she is given to the computer for processing. The output of the program is very specific in nature.
According to the context of this question,
Input: numA = 2
while numA < 30:
numA = numA * 5
print(numA)
Output: numA = 2 × 5 = 10 which is lesser than 30.
Therefore, the output of the following program is 10. This is because it is represented in the program that the value of numA would be less than 30.

D. all the above
Answer: Its A. used to protect the transmission of software and large files to be downloaded
Explanation: Hashing is an algorithm that calculates a fixed-size bit string value from a file. A file basically contains blocks of data. Hashing transforms this data into a far shorter fixed-length value or key which represents the original string. The hash value can be considered the distilled summary of everything within that file. A good hashing algorithm would exhibit a property called the avalanche effect, where the resulting hash output would change significantly or entirely even when a single bit o...

A basic slide size is 16:9 aspect ratio, which is suitable for high-definition TVs and widescreen monitors.
What is widescreen monitor ?The majority of modern high-definition computer displays and televisions use the widescreen 16:9 aspect ratio. The sides are represented by the "9," while the top and bottom are represented by the "16." The ratio of a monitor's or TV's width to height is indicated by the numbers separated by a comma.
The majority of widescreen displays their material using the just-adopted 16:9 aspect ratio. All the movies, and video games you watch or play will be in HD unless the content you're watching was made in a 4:3 aspect ratio.
According to research, utilizing several screens or enlarging monitors makes them far more painful for the eyes.

The assignment
Your job in this assignment is to write a program that takes a message as a string and reduces the number of characters it uses in two different set ways. The first thing your program will do is ask the user to type a message which will be stored as a String. The String entered should be immediately converted to lowercase as this will make processing much easier. You will then apply two different algorithms to shorten the data contained within the String.
Algorithm 1
This algorithm creates a string from the message in which every vowel (a, e, i, o, and u) is removed unless the vowel is at the very start of a word (i.e., it is preceded by a space or is the first letter of the message). Every repeated non-vowel character is also removed from the new string (i.e., if a character appears several times in a row it should only appear once at that location). So for example the string "I will arrive in Mississippi really soon" becomes "i wl arv in mssp rly sn".
After applying this algorithm, your program should output the shortened message, the number of vowels removed, the number of repeated non-vowel characters removed, and how much shorter the shortened message is than the original message. The exact format in which the program should print this information is shown in the sample runs.
Algorithm 2
This algorithm creates a string by taking each unique character in the message in the order they first appear and putting that letter and the number of times it appears in the original message into the shortened string. Your algorithm should ignore any spaces in the message, and any characters which it has already put into the shortened string. For example, the string "I will arrive in Mississippi really soon" becomes "8i1w4l2a3r1v2e2n1m5s2p1y2o".
After applying this algorithm, your program should output the shortened message, the number of different characters appearing, and how much shorter the shortened message is than the original message. The exact format in which the program should print this information is shown in the sample runs.
Sample Run 1
Type the message to be shortened
This message could be a little shorter
Algorithm 1
Vowels removed: 11
Repeats removed: 2
Algorithm 1 message: ths msg cld b a ltl shrtr
Algorithm 1 characters saved: 13
Algorithm 2
Unique characters found: 15
Algorithm 2 message: 4t2h2i4s1m5e2a1g1c2o1u3l1d1b2r
Algorithm 2 characters saved: 8
Sample Run 2
Type the message to be shortened
I will arrive in Mississippi really soon
Algorithm 1
Vowels removed: 11
Repeats removed: 6
Algorithm 1 message: i wl arv in mssp rly sn
Algorithm 1 characters saved: 17
Algorithm 2
Unique characters found: 13
Algorithm 2 message: 8i1w4l2a3r1v2e2n1m5s2p1y2o
Algorithm 2 characters saved: 14
Milestones
As you work on this assignment, you can use the milestones below to inform your development process:
Milestone 1: Set up a program that takes a string input and converts all the letters to lowercase. Start implementing algorithm 1: create a counter variable and iterate through the characters of the String, incrementing this each time a vowel is encountered which is not preceded by a space or is at the start of the String. So at the end of the loop this counts the number of vowels that are not at the start of a word.
Milestone 2: Add further conditions (using else if) in your loop to count any non-vowel characters which appear immediately after the same character. Make a new empty String to hold the shortened message at the start of the code, then add a final else condition in the loop to add all characters which were not vowels or repeated letters to this String. Then print the statements for algorithm 1 using your counts and shortened message.
Milestone 3: Start implementing algorithm 2 by writing code that iterates through the String and checks that each character is not a space and has not already appeared in the word before that point. You will need to use nested loops - an outer loop to iterate through the String characters and an inner loop that looks through the previous characters up to that point - and a flag variable to record if a letter was found in the inner loop. Use a counter variable to count all such "unique" characters in the String.
Milestone 4: Add a second inner loop inside the outer loop from the previous which counts all appearances of a character that passes the tests from milestone 3. Add the character and the number of times it appears to another shortened message String (which should start as blank String). Finally, print the statements for algorithm 2 using your unique character count and shortened message.
Answer:
Scanner scan = new Scanner(System.in);
System.out.println("Type the message to be shortened");
String msg = scan.nextLine();
System.out.println();
msg = msg.toLowerCase();
String newStr = "";
System.out.println("Algorithm 1");
int vowels = 0;
int repeats = 0;
for(int i = 0; i < msg.length(); i++)
{
if((msg.substring(i, i +1).equals("a") || msg.substring(i, i+1).equals("e") || msg.substring(i, i +1).equals("i") || msg.substring(i, i+1).equals("o") || msg.substring(i, i +1).equals("u")))
{
if(i != 0 && !msg.substring(i -1, i).equals(" "))
{
vowels++;
}
else
newStr += msg.substring(i, i +1);
}
else if(i != 0 && msg.substring(i, i +1).equals(msg.substring(i -1, i)))
{
repeats++;
}
else
{
newStr += msg.substring(i, i +1);
}
}
System.out.println("\nAlgorithm 1");
System.out.println("Vowels removed: " + vowels);
System.out.println("Repeats removed: " + repeats);
System.out.println("Algorithm 1 message: " + newStr);
System.out.println("Algorithm 1 characters saved: " + (vowels + repeats));
algorithm2(msg);
}
public static void algorithm2(String msg)
{
String alg2Msg = "";
int uniqueLetters = 0;
// Iterate through each letter in msg
for(int i=0; i < msg.length(); i++)
{
String ltr = msg.substring(i,i+1);
// Only process if this character is not a space
if(!ltr.equals(" "))
{
/* Check whether this character has already appeared by
* iterating through characters from start up to the current
* letter and using a boolean flag variable.
*/
boolean alreadyUsed = false;
for(int j=0; j<i; j++)
{
if(msg.substring(j,j+1).equals(ltr))
{
alreadyUsed = true;
}
}
/* If this character hasn't already appeared,
* iterate through the rest of the characters
* and count how many times it appears.
