1题目 A peak element is an element that is greater than its neighbors. Given an input array where num[i] ≠ num[i+1], find a peak element and return its index. The array may contain multiple peaks, in that case return the index to any one of the peaks i…
二分法相关 153. Find Minimum in Rotated Sorted Array Suppose a sorted array 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. You may assume no duplicate exists in the array. (M…
示例 2: 输入: nums = [1,2,1,3,5,6,4] 输出: 1 或 5 解释: 你的函数可以返回索引 1,其峰值元素为 2:   或者返回索引 5, 其峰值元素为 6. 说明: 你的解法应该是 O(logN) 时间复杂度的. 二分法: 如果中间的是峰值直接返回,如果不是,那么两边较大的那一侧是存在峰值的. class Solution { public: int findPeakElement(vector<int>& nums) { int len = nums.siz…

There is an integer array which has the following features: The numbers in adjacent positions are different. A[0] < A[1] && A[A.length - 2] > A[A.length - 1]. We define a position P is a peek if: A[P] > A[P-1] && A[P] > A[P+1]…
Hi 大家,这道题是lintcode上的find peak element的题,不是leecode的那道, 这两道题是有区别的,这道题的题目中说明了:只有左右两侧的数都小于某个元素,这种才是峰值, 而leetcode的题,是只要找到个最大值就行,可以是[1,2]这种. There is an integer array which has the following features: The numbers in adjacent positions are different. A[0] <…
