Given an integer array nums, move all 0's to the end of it while maintaining the relative order of the non-zero elements. Note that you must do this in-place without making a copy of the array.

Move Zeroes
Given an integer array nums, move all 0's to the end of it while maintaining the relative order of the non-zero elements. Note that you must do this in-place without making a copy of the array.
Example 1:
Input: [0,1,0,3,12]
Output: [1,3,12,0,0]
Input
arr =[0,1,0,3,12]
Move all zeros to end, maintain order of non-zeros
