leetcode第27题移除元素--快慢指针

class Solution(object):
    def removeElement(self, nums, val):
        slow=fast=0
        n=len(nums)
        while fast

 又是easy重拳出击的一天。宫水三叶的代码

class Solution(object):
    def removeElement(self, nums, val):
        slow=0
        for fast in nums:
            if fast!=val:
                nums[slow]=fast
                slow+=1
        return slow
