LeetCode上的原题,请参见我之前的博客Find Peak Element。 解法一: classSolution {public:/** * @param A: An integers array. * @return: return any of peek positions.*/intfindPeak(vector<int>A) {intleft =0, right = A.size() -1;while(left <right) {intmid = left + (right - left)...
A peak element is an element that is greater than its neighbors. Given an input array wherenum[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 fine. You may imagine thatnum[...

lintcode:Find Peak Element 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:...
[Array]Find Peak Element 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 tha......
The index of first peak element in the array is: 3 The task is to write a C program that finds the index of the first peak element in a given array. A peak element is defined as an element that is greater than its neighbors. The program should traverse the array, identify the first...
