UVA-10391(字符串检索)

题意：

给定一个字典，要求找出所有的复合词;

思路：

用map把词都存起来,再把词拆开看是否是出现过的单词;

AC代码:

#include <bits/stdc++.h>
#include <iostream>
#include <cstdio>
#include <cstring>
#include <algorithm>
#include <cmath>
 
using namespace std;
 
#define For(i,j,n) for(int i=j;i<=n;i++)
#define mst(ss,b) memset(ss,b,sizeof(ss));
 
typedef  long long LL;
 
template<class T> void read(T&num) {
    char CH; bool F=false;
    for(CH=getchar();CH<''||CH>'';F= CH=='-',CH=getchar());
    for(num=;CH>=''&&CH<='';num=num*+CH-'',CH=getchar());
    F && (num=-num);
}
int stk[], tp;
template<class T> inline void print(T p) {
    if(!p) { puts(""); return; }
    while(p) stk[++ tp] = p%, p/=;
    while(tp) putchar(stk[tp--] + '');
    putchar('\n');
}
 
const LL mod=1e9+;
const double PI=acos(-1.0);
const int inf=1e9;
const int N=12e4+;
const int maxn=1e3+;
const double eps=1e-;
 
int n;
string s[N];
map<string,int>mp;
int main()
{
        int cnt =;
        while(cin>>s[++cnt])
        {
            mp[s[cnt]]=;
        }
        string a,b;
        For(i,,cnt)
        {
            int len=s[i].size();
            For(j,,len-)
            {
                a=s[i].substr(,j+);
                b=s[i].substr(j+);
                if(mp[a]&&mp[b])
                {
                    cout<<s[i]<<"\n";
                    break;
                }
            }
        }
        return ;
}
