原题链接,点我 该题解题参考博客 和Search in Rotated Sorted Array唯一的区别是这道题目中元素会有重复的情况出现.不过正是因为这个条件的出现,出现了比较复杂的case,甚至影响到了算法的时间复杂度.原来我们是依靠中间和边缘元素的大小关系,来判断哪一半是不受rotate影响,仍然有序的.而现在因为重复的出现,如果我们遇到中间和边缘相等的情况,我们就丢失了哪边有序的信息,因为哪边都有可能是有序的结果.假设原数组是{1,2,3,3,3,3,3},那么旋转之后有可能是{3,3…

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…
