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…
题目 Given an array nums and a value val, remove all instances of that value in-place and return the new length. Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory. The order of…
Given an array and a value, remove all instances of that value in place and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. The order of elements can be changed. It doesn't matter…
Given an integer array of size n, find all elements that appear more than ⌊ n/3 ⌋ times. The algorithm should run in linear time and in O(1) space. 求主元素,这次的是大于sz/3就算是主元素,可以分为两轮查找,第一轮先查找元素数目较多的两个元素(可能不属于主元素),第二次再遍历来查找上面两个元素是否符合条件,代码如下: class Solution…
Given an array and a value, remove all instances of that value in place and return the new length. The order of elements can be changed. It doesn't matter what you leave beyond the new length. ps:这个题目同样是一个双指针的问题,比较简单,代码如下所示 class Solution { public: i…
一.WCF的简单介绍 Windows Communication Foundation(WCF)是由微软发展的一组数据通信的应用程序开发接口,可以翻译为Windows通讯接口,它是MS为SOA (Service Oriented Architecture)战略而设计的一套完整的技术框架.它是一种统一的编程模型,用来为微软平台编写分布式(Distributed)应用.涵盖了之前出现的多种技术,如ASMX,Remoting,MSMQ等等. 优点: 1.整合了多项技术,是MS SOA产品的集大成者…
