题目链接:http://codeforces.com/contest/931/problem/D 题目大意:给你一颗树,每个节点都会长苹果,然后每一秒钟,苹果往下滚一个.两个两个会抵消苹果.问最后在根节点能收到多少个苹果. 解题思路:昨天是我想复杂了,其实就是统计下每层的苹果数,若是奇数则答案+1.因为最终这些苹果都会滚落汇聚到根节点,所以在滚落过程中肯定会碰撞并相消无论苹果是怎么分布的. 代码: #include<iostream> #include<cstdio> #inclu…

题意给你一颗树,开始时每个结点都有一个小球,每一秒钟每个小球都往上滚一层,当两个球在同一个结点的时候会被消去,如果三个五个七个等在同一个结点的化消去后只剩一个. 分析 这对我来说就TM是英语阅读理解哇!赛场上读题读到懵逼啊! 最容易想到的是一个O(N^2)的算法,最深由maxd层,从第一层枚举到maxd层然后进行DFS,来计算每一层的小球最后落下来还剩几个,但是这样肯定会被卡掉.然后就再想一个类似贪心的方法,直接dfs计算每一层的小球数量,如果偶数则全部会被消掉,如果是奇数则会剩一个.这样做为什…

题目: 给出一个树,这棵树上每个结点每一秒都会结出一颗果实,果实每经过一秒就会落向下一个结点,如果一个结点在同一时刻上的果实两两抵消,问最后在根节点处一共有多少个果实. 思路: dfs直接搜索统计这棵树的每一层上有多少个果实就可以了.如果是奇数个ans++,偶数个不作处理. 代码: #include <bits/stdc++.h> #include <cstdio> #include <cstring> #include <iostream> #includ…

什么是arguments arguments 是是JavaScript里的一个内置对象,它很古怪,也经常被人所忽视,但实际上是很重要的.所有主要的js函数库都利用了arguments对象.所以agruments对象对于javascript程序员来说是必需熟悉的. 所有的函数都有属于自己的一个arguments对象,它包括了函所要调用的参数.他不是一个数组,如果用typeof arguments,返回的是'object'.虽然我们可以用调用数据的方法来调用arguments.比如length,还有…

来自CSDN的Rachel Zhang 4. Improved SAP 算法 本次介绍的重头戏.通常的 SAP 类算法在寻找增广路时总要先进行 BFS,BFS 的最坏情况下复杂度为 O(E),这样使得普通 SAP 类算法最坏情况下时间复杂度达到了 O(VE2).为了避免这种情况,Ahuja 和 Orlin 在1987年提出了Improved SAP 算法,它充分利用了距离标号的作用,每次发现顶点无出弧时不是像 Dinic 算法那样到最后进行 BFS,而是就地对顶点距离重标号,这样相当于在遍历的同…

SocketServer 在上一篇文章中我们学习了利用socket模块创建socket通信服务,但细心学习后就会发现利用socket模块创建的服务无法进行多进程的处理,当需要进行大量请求处理时,请求就会阻塞在队列中,甚至发生请求丢弃.并且如果我们需要大量的socket时,就需要重复创建许多socket.绑定端口..... ,对于程序员来说意味着重复书写大量无意义代码. 那有没有一种方式既能简化书写流程又能实现多线程开发呢 ? 答案是肯定的,这就是SocketServer模块. SocketSer…
