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 is fi…

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] <…
