题目连接:10986 - Sending email 题目大意:给出n,m,s,t,n表示有n个点,m表示有m条边,然后给出m行数据表示m条边,每条边的数据有连接两点的序号以及该边的权值,问说从点s到点t的最短路径是多少. 解题思路:本题应该是无环正权值的一个图,并且本题如果直接用Dijkstra算法去做的话超时,所以一定要用优先队列去进行优化,<算法竞赛入门经典>中介绍了这种写法,唯一变动的地方就是有向图变成了无向图. #include <stdio.h> #include &l…

题目大意:网络中有n个SMTP服务器,有m条电缆将它们相连,每条电缆传输信息需要一定的时间.现在给出信息的起点和终点,计算所需的最小时间. 有权图上的单源最短路问题(Single-Source Shortest Path, SSSP),直接使用Dijkstra算法. #include <cstdio> #include <vector> #include <queue> using namespace std; typedef pair<int, int>…

基本的最短路问题 就是数据需要稍微处理一下.(N比较大)dijkstra也要优化.不优化应该会T: #include <map> #include <set> #include <list> #include <cmath> #include <ctime> #include <deque> #include <stack> #include <queue> #include <cctype> #i…

这个题目真是伤透脑筋了,一直RE,连着改了好几个版本,又是spfa,又是单调队列dijkstra+单调队列,总是不过,后来发现M开小了,双向边应该开m的两倍,悲剧啊!!!以后不管怎样,数组一定要尽量开大点. 折磨的真是痛苦,不过发现了一样好东西,http://uvatoolkit.com/problemssolve.php uva一个测试工具,输入数据能够给出正确结果,以后不用辛苦到网上找AC代码了,直接输入结果. #include <cstdio> #include <cstring&…

The mailx or mail command in Linux is still providing service for guys like me, especially when we need to send email automatically by script. gmail is great. Now, how to use gmail’s smtp in mailx/mail? gmail is a little special since gmail’s smtp se…

Spring comes with a useful ‘org.springframework.mail.javamail.JavaMailSenderImpl‘ class to simplify the e-mail sending process via JavaMail API. Here’s a Maven build project to use Spring’s ‘JavaMailSenderImpl‘ to send an email via Gmail SMTP server.…

E-mail functionality uses the Apache Commons Email library under the hood. You can use theplay.libs.Mail utility class to send e-mail very easily. A simple e-mail: SimpleEmail email = new SimpleEmail(); email.setFrom("sender@zenexity.fr"); email…
