Write a program to Reverse the digits of an integer.
Input : num = 12345
Output: 54321
Input : num = 876
Output: 678
Algorithm:
Input: num
(1) Initialize rev_num = 0
(2) Loop while num > 0
(a) Multiply rev_num by 10 and add remainder of num
divide by 10 to rev_num
rev_num = rev_num*10 + num%10;
(b) Divide num by 10
(3) Return rev_num
