283. 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: nums = [0,1,0,3,12] Output: [1,3,12,0,0]
Example 2:
Input: nums = [0] Output: [0]
1 <= nums.length <= 104-231 <= nums[i] <= 231 - 1
