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] <…

A peak element is an element that is greater than its neighbors. Given an input array nums, where nums[i] ≠ nums[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 pea…

75. Find Peak Element [medium] 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-…

题目 寻找峰值 你给出一个整数数组(size为n),其具有以下特点: 相邻位置的数字是不同的 A[0] < A[1] 并且 A[n - 2] > A[n - 1] 假定P是峰值的位置则满足A[P] > A[P-1]且A[P] > A[P+1],返回数组中任意一个峰值的位置. 样例 给出数组[1, 2, 1, 3, 4, 5, 7, 6]返回1, 即数值 2 所在位置, 或者6, 即数值 7 所在位置. 注意 数组可能包含多个峰值,只需找到其中的任何一个即可 解题 直接遍历 Java…
