3. The question
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].
4 My code(AC)
public class Solution { public void moveZeroes(int[] nums) { if (nums == null) return; int len = nums.length; int i = 0, step = 0; while (i < len) { if (nums[i] == 0) { step++; }else{ nums[i - step] = nums[i]; } i++; } for (int index = 0; index < step; index++) { nums[len - index - 1] = 0; } } }
