Given an array
nums
, write a function to move all 0
's to the end of it while maintaining the relative order of the non-zero elements.
For example, given
nums = [0, 1, 0, 3, 12]
, after calling your function, nums
should be [1, 3, 12, 0, 0]
.
Note:
- You must do this in-place without making a copy of the array.
- Minimize the total number of operations.
