Question

Using a while loop, create an algorithm extractDigits that prints the individual digits of a positive integer.

Answer 1

The question involves writing an algorithm using a while loop to extract and print the digits of a positive integer from least significant to most significant, which is associated with high school level Computers and Technology.

Step-by-step explanation:

The question requires an algorithm that uses a while loop to separates the digits of a given positive integer. Here's a simple algorithm for extracting and printing each digit of a positive integer:

• Start with the positive integer that you want to extract digits from.
• Use a while loop to continue the process as long as the number is greater than 0.
• Inside the loop, use the modulus operator (%) to get the last digit of the number.
• Print the digit obtained from the modulus operation.
• Divide the number by 10 to remove the last digit.
• Repeat the loop until the number is reduced to 0.
• In pseudocode, your algorithm
• extractDigits
• might look something like this:

function extractDigits(number):
while number > 0:
digit = number % 10
print(digit)
number = number // 10
end function

This algorithm prints each digit starting from the least significant digit (the ones place) to the most significant digit (the highest place value).

Answer 2

The algorithm is as follows

1. Start

2. Declare Integer N

3. Input N

4. While N > 0:

4.1 Print(N%10)

4.2 N = N/10

5. Stop

Step-by-step explanation:

This line starts the algorithm

1. Start

This declares an integer variable

2. Declare Integer N

Here, the program gets user input N

3. Input N

The while iteration begins here and it is repeated as long as N is greater than 0

4. While N > 0:

This calculates and prints N modulus 10; Modulus of 10 gets the individual digit of the input number

4.1 Print(N%10)

This remove the printed digit

4.2 N = N/10

The algorithm ends here

5. Stop

Bonus:

The algorithm in Python is as follows:

n = 102

while n>0:

print(int(n%10))

n= int(n/10)
