题目要求

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.

题目分析及思路

给定一个数组,要求将这个数组中所有的0移到数组末尾并保持非零元素相对位置不变。可以先得到零元素的个数,然后循环将零进行移除和在末尾添加。

python代码

class Solution:

def moveZeroes(self, nums: List[int]) -> None:

"""

Do not return anything, modify nums in-place instead.

"""

zeros = nums.count(0)

for _ in range(zeros):

nums.remove(0)

nums.append(0)
