题目很简单.给一个有向图,求两点间的最大流量与任意一条路中的最大流量的比值. 最大流不说了,求出单条流量最大的路径可以用类似Spfa的方法来搞,保存到达当前点的最大流量,一直往下更新即可. 召唤代码君: #include <iostream> #include <cstdio> #include <cstring> #include <vector> #define maxn 1010 #define Inf ~0U>>1 using names…

use fgets, and remove the potential '\n' in the string's last postion. (main point) remove redundancy there must be a stack, at first sight, you need a stack of type myNode, but think deeper, matrix multiplication is valid only if A.c=B.r, then the n…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=4240 A city is made up exclusively of one-way steets.each street in the city has a capacity,which is the minimum of the capcities of the streets along that route. The redundancy ratio from point A to poi…

设计和开发可以掌控客户端的分布式服务端程序是件幸事,可以把很多事情交给客户端来做,而且可以做的很优雅.角色决定命运,在互联网架构中,web server必须冲锋在前,注定要在多浏览器版本以及协议兼容性方面呕心沥血.但要是做了web server的backend,就会好很多,可以让服务端程序独善其身,分布式的功能特性都由客户端来支持和实现.memcache就是这样的设计模式.memcache是后台架构必备的利器,关于其原理及源码分析可以直接google之,在此不再多说.最近项目中要考虑冗余和容错的…

(17)采用CRC进行差错校验,生成多项式为G(X)=X4+X+1,信息码字为10111,则计算出的CRC校验码是  (17)  .A．0000  B．0100   C．0010   D．1100试题解析:   答案:(17)D CRC(Cyclic Redundancy Check)循环冗余校验码 是常用的校验码,在早期的通信中运用广泛,因为早期的通信技术不够可靠(不可靠性的来源是通信技术决定的,比如电磁波通信时受雷电等因素的影响),不可靠的通信就会带来‘确认信息’的困惑,书上提到红军和蓝军通…
