283. Move Zeroes

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.

public class Solution {
public void moveZeroes(int[] nums) {
int cnt = 0, pos = 0;
// 将非0数字都尽可能向前排
for(int i = 0; i < nums.length; i++){
if(nums[i] != 0){
nums[pos]= nums[i];
pos++;
}
}

// 将剩余的都置0
for(;pos<nums.length; pos++){
nums[pos] = 0;
}
}
}
