快慢指针 时间复杂度 O(N)

class Solution:
    def moveZeroes(self, nums: List[int]) -> None:
        j = 0
        for i in range(len(nums)):
            if nums[i] != 0:
                if i != j:
                    nums[i], nums[j] = nums[j], nums[i]
                j = j + 1

两个循环 时间复杂度 O(N)

class Solution:
    def moveZeroes(self, nums: List[int]) -> None:
        j = 0
        for i in range(len(nums)):
            if nums[i] != 0:
                nums[j] = nums[i]
                j += 1
        
        for i in range(j, len(nums)):
            nums[i] = 0
