Java Program - Reverse digits of a given Integer

Input: MyNum
Step 1: Initialize the RevNum = 0
Step 2: Iterate over MyNum while it is greater than zero.
   Step 2a: Calculate remainder of MuNum / 10
   Step 2b: Update RevNum by RevNum * 10 + remainder
   Step 2c: Update MyNum by MyNum / 10
Step 3: Return RevNum

Input: 564

RevNum: 0
Iteration 1: 
    Remainder: 564 % 10 = 4
    RevNum: 0 * 10 + 4 = 4
    MyNum: 564 / 10 = 56

Iteration 2: 
    Remainder: 56 % 10 = 6
    RevNum: 4 * 10 + 6 = 46
    MyNum: 56 / 10 = 5

Iteration 3: 
    Remainder: 5 % 10 = 5
    RevNum: 46 * 10 + 5 = 465
    MyNum: 5 / 10 = 0

return RevNum = 465
