【题目】 Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2). You are given a target value to search. If found in the array return its index, otherwise return -1. You may assume no duplicate exists in ...

leetcode第一刷_Search in Rotated Sorted Array,旋转数组的查找问题。从头開始扫一遍。O(N)的复杂度,一般也能过,甚至先排序下面,再二分都能过。只是这道题的目的当然不在于此。想一下旋转之后对我们的查找产生了什么影响。假设没旋转过,我们直接比較target与A[middle]
leetCode 33. Search in Rotated Sorted Array(c语言版本) bingo酱 I am a fighter 来自专栏 · leetcode每日斩 题目大意: 给定一个旋转升序的数组,所谓旋转就是假设把头和尾连接起来,然后找到最小那个数开始,往后开始就是升序的,直到再回到最小那个数为止。这样看起来就像一个环一样。 然后,现在给定一个数,...
