解析:水题勿喷。。。set的简单应用~~~
AC代码:
#include <bits/stdc++.h>
using namespace std;
const int maxn = 10005;
set<string> p;
int main(){
#ifdef sxk
freopen("in.txt", "r", stdin);
#endif // sxk
string t, s;
while(getline(cin, s) && s != "#"){
int n = s.size();
p.clear();
for(int i=0; i<n; i++){
t = "";
while(s[i] >= 'a' && s[i] <= 'z') t += s[i++];
if(t != "") p.insert(t);
}
printf("%d\n", p.size());
}
return 0;
}
