//我写的

#include <iostream>
#include <string>
using namespace std;
int main()
{
string code[100];
int t = 0;
int cas = 0;
bool Is = true;
while(cin >> code[t])
{
if(code[t] == "9")
{
++cas;
if(Is)
cout << "Set " << cas << " is immediately decodable" << endl;
else
cout << "Set " << cas << " is not immediately decodable" << endl;
Is = true;
t = 0;
continue;

}
for(int i = 0 ; i < t; i++)
{
//cout << code[t].find(code[i]) << endl;
if(code[t].find(code[i]) == 0)
{
Is =false;
break;
}
}
t++;

}
return 0;
}

 

我就不明白为什么我写的会错。。。感觉都一样的阿。。
