Write a program to an integer as an input and reverse that integer.

Input:
A single integer.

Output:
Reverse number of that integer.

Example:

Input:
54321

Output:
12345

Python Code With Explanation:

#The program takes an integer input from the user using the input() function

#and converts it into an integer using the int() function.

num = int(input())

#We initialize a variable reverse to 0 to store the reverse of the input integer.

reverse = 0

#We use a while loop to extract each digit of the input integer starting from the least significant digit 

#(i.e., the digit in the ones place) 

#and add it to the reverse variable after shifting its existing digits by one place to the left.

while num > 0:

    digit = num % 10

    reverse = (reverse * 10) + digit

    

#We update the input integer by removing the least significant digit using integer division (//).

#The loop continues until all digits of the input integer have been processed.

    num //= 10

# print the value of reverse which contains the reverse of the input integer.

print(reverse,end="")
