题目: Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). Find the minimum element. The array may contain duplicates. 思路: 1.题目中指出sorted array,find target使用二分法.…

Leetcode之二分法专题-153. 寻找旋转排序数组中的最小值(Find Minimum in Rotated Sorted Array) 假设按照升序排序的数组在预先未知的某个点上进行了旋转. ( 例如,数组 [0,1,2,4,5,6,7] 可能变为 [4,5,6,7,0,1,2] ). 请找出其中最小的元素. 你可以假设数组中不存在重复元素. 示例 1: 输入: [3,4,5,1,2] 输出: 1 示例 2: 输入: [4,5,6,7,0,1,2] 输出: 0 很明显,我们需要用二分查找…
