Leetcode上的Partition List问题是什么? Partition List问题的时间复杂度是多少? 题目大意 给定一个链表以及一个目标值,把小于该目标值的所有节点都移至链表的前端,大于或等于目标值的节点移至链表的尾端,同时要保持这两部分在原先链表中的相对位置。 解题思路 此题并不难,并且可以帮助理解链表。 两个指针,一个负...
因为只要确定下前两个数,接下来就可以用N时间判断整个str是否满足条件了,确定前两个数需要N^2 空间上递归最深是O(N)层,也只需要返回一个符合的partition 下一题比这题在调用递归函数的条件判断更复杂 LeetCode-282. Expression Add Operators def addOperators(self, num: str, target: int) -> List[str]...
