放弃了,,,这题怎么做的啊,,,我的map果断tle,,,,难道要写hash,,或者trie,,,然后写一些rb树,avl之类的东西吗?500个句子就tle,,真郁闷,,?扔下我的代码,,谁帮忙看看是不是哪里死循环了??#pragma warning(disable:4786)
#include <iostream>
#include <map>
#include <string>
#include <cstring>
using namespace std;
const int N=1111;
struct node
{
map<string,int>m;
char s[11];
}nod[20000];
void dfs(int u,int dep)
{
for(map<string,int>::iterator i=nod[u].m.begin();i!=nod[u].m.end();i++)
{
for(int j=1;j<=dep;j++)
putchar(' ');
printf("%s\n",(i->first).c_str());
dfs(i->second,dep+1);
}
}
int main()
{
int n;
scanf("%d",&n);
char c[N];
int i,j,id=0,num[N];
for(i=1;i<=n;i++)
{
scanf("%s",c);
int end=0;
num[++end]=0;
for(j=0;c[j];j++)
if(c[j]=='\\')
c[j]=0,num[++end]=j+1;
if(!nod[0].m.count(c))
nod[0].m[c]=++id,strcpy(nod[id].s,c);
int p=nod[0].m[c];
for(j=2;j<=end;j++)
{
if(!nod[p].m.count(c+num[j]))
nod[p].m[c+num[j]]=++id,strcpy(nod[id].s,c+num[j]);
p=nod[p].m[c+num[j]];
}
}
dfs(0,0);
return 0;
}
