Your solution should be in logarithmic complexity. https://leetcode.com/problems/find-peak-element/ 提示说要求指数级的复杂度,我就想不能够吧... 原来是先入为主了,没说求最高的峰顶,只要是峰顶,随便哪个都可以Orz。 我原以为是有多个最高的峰顶,输出哪个都可以,原来要求这么随便,这样真的没问题吗。
Leetcode** 162. Find Peak Element Description:A peak element is an element that is strictly greater than its neighbors. Given an integer arraynums, find a peak element, and return its index. If the array contains multiple peaks, return the index toany of the peaks....
