传送门 题意 给出x个a区间和y个b区间,询问a和b交区间的子区间长度为m的个数 分析 类似于双指针,具体见代码 trick 代码 #include <bits/stdc++.h> using namespace std; #define F(i,a,b) for(int i=a;i<=b;++i) #define R(i,a,b) for(int i=a;i<b;++i) #define mem(a,b) memset(a,b,sizeof(a)) #pragma comment…

公司的OA从零开始进行开发,继简单的单点登陆.角色与权限.消息中间件之后,轮到在线即时通信的模块需要我独立去完成.这三周除了逛网店见爱*看动漫接兼职,基本上都花在这上面了.简单地说就是用MVC4基于长轮询实现(伪)即时通信,利用BootMetro搭建即时聊天系统,同时跨域组件化之后今晚移植到了Azure上方便周末进行第一次迭代的公网测试,地址在http://indreamchat.cloudapp.net/.有兴趣的朋友可以上去送测试数据,剥离了认证登陆,简单地伪装了一个...一个...怎么说,…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=5071 解题报告:一个管理聊天窗口的程序,一共有八种操作,然后要注意的就是Top操作只是把编号为u的窗口标记为一种特殊的状态,在这种特殊的状态下优先级是最高的,聊天都是跟这个聊,而这个窗口并没有在实际上被提到最前面.还有就是每句后面都有句号.我本来可以1A的,但就是因为没看这个,所以一直WA也找不到原因. 暴力模拟就可以了,因为点最多只有5000个,不会超时,维护一个队列就可以了,但我为了方便判断是不…

题意很简单,就是寻找一个字符串中连续的最长包含不同字母的子串. 其实用最朴素的方法,从当前字符开始寻找,找到以当前字符开头的最长子串.这个方法猛一看是个n方的算法,但是要注意到由于字符数目的限制,其实这是个O(Cn)的算法,最长也不过是C长度.所以我觉得普通方法应该是能过的. 于是写了一个,字符数目最大也不超过256所以代码如下: class Solution { public: int lengthOfLongestSubstring(string s) { ; ;i<s.length();i…
