Given N,  reverse the digits of N.
 
Example 1:
Input: 200
Output: 2
Explanation: By reversing the digts of 
number, number will change into 2.
Example 2:
Input : 122
Output: 221
Explanation: By reversing the digits of 
number, number will change into 221.
 
Your Task:
You don't need to read or print anything. Your task is to complete the function reverse_digit() which takes N as input parameter and returns the reversed number.
