peak

题目地址： https://oj.leetcode.com/problems/find-peak-element/ 题目内容： 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 num[-1] = num[n] = -∞ . For example, in array [1, 2, 3, 1] , 3 is a peak element and your function should return the index number 2. click to show spoilers. Note: Your solution should be in logarithmic complexity. 方法： 有两点需要注意的： 0、复杂度要为O(log n) 1、注意审题 我第一次做

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 num[-1] = num[n] = -∞. For example, in array [1, 2, 3, 1], 3 is a peak element and your function should return the index number 2. 这道题是水题，注意边界条件即可。 C++ Code: class Solution { public : int findPeakElement( const vector < int > &num) { if (num.size() == 1 ) { return 0 ; } else if (num.size() == 2 ) { return num[ 0 ] > num[ 1

最近接触到SD-WAN项目，选用的是Silver Peak产品，原来我在70-743中接触过微软的SD-WAN产品，感觉微软也是用一个类似的硬件盒子，接到你的互联网的前端，把公司内部的虚机平台的VLAN信息和Azure平台做一个很好的管理。 在微软的产品中，需要配置SDN网络控制器，SDN的SLB，SDN RS网关，当然还可以做QOS控制SDN虚拟网络带宽等。 微软的SDN有两种管理方式，一个是Powershell的，一个是通过System Center VMM进行管理。 在百度上，只能找到关于silver peak的一页资料，呵呵，几乎为零的技术支持。当然对于这个产品的理解只能在使用过程中总结，管理界面应该是Web样子的。就是假设我们通过一个小盒子样的前端，通过互联网给接入到一个专有的网络中，实际感觉就是不是MPLS专线好用，云平台。 以下就是这个产品的介绍，目前我就只能理解到这一点，以后有实际经验再更新吧。 来源： 51CTO 作者： raincity 链接： https://blog.51cto.com/shadingyu/2453097

162. Find Peak Element 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 peaks is fine. You may imagine that nums[-1] = nums[n] = -∞ . Example 1: Input: nums = [1,2,3,1] Output: 2 Explanation: 3 is a peak element and your function should return the index number 2. Example 2: Input: nums = [1,2,1,3,5,6,4] Output: 1 or 5 Explanation: Your function can return either index number 1 where the peak
