Given the sorted rotated arraynumsof unique elements, returnthe minimum element of this array. You must write an algorithm that runs inO(log n) time. Example 1: Input: nums = [3,4,5,1,2] Output: 1 Explanation: The original array was [1,2,3,4,5] rotated 3 times. Example 2: I...
Find Peak Element 一.题目链接:https://leetcode.com/problems/find-peak-element/二.题目大意:给定一个长度为N的一维数组,数组是无序的,要求找到数组中的极大值(或局部最大值),并返回该极大值的下标,并假设 nums[-1] = nums[n] = -∞.;当某元素同时大于它两边的元素时,则该元素是数组中的一个极大...
