how to reverse digits in a given number code example

Example 1: reverse intergers in python

# Get the number from user manually 
num = int(input("Enter your favourite number: "))
 
# Initiate value to null
test_num = 0
 
# Check using while loop
 
while(num>0):
  #Logic
  remainder = num % 10
  test_num = (test_num * 10) + remainder
  num = num//10
 
# Display the result
print("The reverse number is : {}".format(test_num))

Example 2: how to reverse a number in c

#include <stdio.h>
int main() {
    int n, rev = 0, remainder;
    printf("Enter an integer: ");
    scanf("%d", &n);
    while (n != 0) {
        remainder = n % 10;
        rev = rev * 10 + remainder;
        n /= 10;
    }
    printf("Reversed number = %d", rev);
    return 0;
}
