模拟评测机判断答案 先判断有没有不一样的 有的话再提取出 有效子列 看看有没有错的 #include <iostream> #include <cstdio> #include <cstring> #include <string> using namespace std; int t; string a,b,sa,sb; ]; ][]={"Accepted","Presentation Error","Wr…

分析:水题. #include<iostream> using namespace std; #define N 5050 char a[N],b[N],tmp[N]; void Read(char p[]) { getchar(); gets(tmp); while(gets(tmp)) { if(strcmp(tmp,"END")==0) break; if(strlen(tmp)!=0) strcat(p,tmp); strcat(p,"\n");…

这道题TLE了N多次,完全不明白为什么,稍微改了一下,居然过了.使用gets过的,看讨论帖有人还推荐用hash. #include <stdio.h> #include <string.h> #define LOCAL 0 #define MAXNUM 5005 #define isSpace(ch) (ch==' '||ch=='\t'||ch=='\n') char stand[MAXNUM]; char data[MAXNUM]; char word[MAXNUM]; int…

题意:给一系列的输出和标准答案,比较二者是AC,PE或WA 字符串处理还是比较薄弱,目前没什么时间搞字符串专题,所以遇到一题就努力搞懂 #include<cstdio> #include<iostream> #include<algorithm> #include<cstring> #include<cmath> #include<queue> #include<map> using namespace std; #def…

定义&&概念: 啥是并查集,就是将所有有相关性的元素放在一个集合里面,整体形成一个树型结构,它支持合并操作,但却不支持删除操作 实现步骤:(1)初始化,将所有节点的父亲节点都设置为自己,例如pre[1]=1(2)合并,将一个元素或者一集合(两者间有联系)合并到另外一个集合(元素)里面,谁是谁的父亲节点不需要过多在意,视题意而定.(3)查找,在合并时需要运用到查找操作,即查找该元素的父节点,尽量使用路径压缩,可以使并查集更加高效,一旦使用了路径压缩,查询时就会将该查询元素到父亲的边改为直接连…
