一.题目说明 这个题目是33. Search in Rotated Sorted Array,说的是在一个"扭转"的有序列表中,查找一个元素,时间复杂度O(logn). 二.我的解答 这是一个查找,根据复杂度,我们知道只能用二分查找.但由于这个不是一个完全的有序列表,故需要改造.先写出二分查找(来源于数据结构): 二分查找: int search(vector<int>& nums, int target){ if(nums.size()<0) return…

做Leetcode题有一段时间了,但都是断断续续的,到现在才做了30题左右,感觉对自己来说还是有点难度的.希望自己能继续坚持下去,在校招前能解决超过一百题吧. 其实这些题就是用来训练你的解题思路的,做多了的话,才能在校招时面对编程题目,能立即有一个解题的流程,知道这是哪一种类型的题目,一般用什么样的套路,思路会很清晰,比如基础的字符串,数组操作会用到一些排序算法,还有一类是算法思想的题目,比如DP(动态规划),分治,回溯法,贪心等等,多练,多思考,多总结. ‘庖丁解牛,恢恢乎游刃有余’,无他,唯…
