For example, in array[1, 2, 3, 1], 3 is a peak element and your function should return the index number 2. 这也是一道神奇的题目,原本来源是geeksforgeeks,题目提示用对数时间来时间,基本只有二分了。另外题意是找到其中一个peak element,不是全部或者全局的peak元素,这也是可以使用二分的保证。另外...
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 fine. You may imagine that nu...
