Given an arraynums, write a function to move all0's to the end of it while maintaining the relative order of the non-zero elements.
For example, givennums = [0, 1, 0, 3, 12], after calling your function,numsshould 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.
