Move Zeroes

Description

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.

Example:

Input: [0,1,0,3,12]

Output: [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.

Code

class Solution {
    public void moveZeroes(int[] nums) {
        int moveStep = 0;
        for (int i = 0; i < nums.length; i++) {
            if (nums[i] == 0) {
                moveStep++;
                continue;
            }
            if (moveStep != 0) {
                nums[i - moveStep] = nums[i];
                nums[i] = 0;
            }
        }
    }
}
