set去重

使用vector<string>+set去重就能很方便地完成</string>

#include<set>
#include<vector>
#include<iostream>
using namespace std;
using namespace std;
int main()
{
    vector <string> name(2500);
    int i=0;
    int count;
    while(cin>>name[i++]){}
    set <string> s(name.begin(),name.end());
    name.assign(s.begin(),s.end());
    count = name.end()-name.begin()-1;
    printf("%d",count);
    return 0;
}
