Question

Write a program (wap) that will reverse the digits of an input infeger.

sample input 13579 4321
sample output 97531 1234

Answer 1

You can reverse the digits of an input integer by using a loop to extract the last digit and rebuilding the number in reverse order.

Step-by-step explanation:

To reverse the digits of an input integer, you can use a loop to extract the last digit of the number and then multiply the previously reversed number by 10 and add the extracted digit. Here's a program in Python that accomplishes this:

num = int(input('Enter an integer: '))
reversed_num = 0

while num > 0:
digit = num % 10
reversed_num = reversed_num * 10 + digit
num = num // 10

print('Reversed number:', reversed_num)

In this program, we use the modulus operator (%) to extract the last digit from the integer. We then use the integer division operator (//) to remove the extracted digit from the original number. The reversed number is built by multiplying the previously reversed number by 10 and adding the extracted digit.
