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: You must do this in-place without making a copy of the array.
Examples
Example 1
Input: nums = [0,1,0,3,12]
Output: [1,3,12,0,0]
Example 2
Input: nums = [0]
Output: [0]
Example 3
Input: nums = [1,2,3]
Output: [1,2,3]
No zeroes to move.
Constraints
1 <= nums.length <= 10^4-2^31 <= nums[i] <= 2^31 - 1
How the tests work: the answer is checked by reading your modified input, not your return value.
