http://www.spoj.pl/problems/GNY07A/

and this is all i could write :(and it didn't work !)
#include <cstdlib>
#include <iostream>
using namespace std;

int main(int argc, char *argv[])
{int N;
int x;
cin>>N;
string s;
for (int i=0;i<N;i++)
{
cin>>x;
cin>>s;

int w=1;

s.erase((x-1),1);
cout<<w++<<" "<<s<<endl;

}



system("PAUSE");

return EXIT_SUCCESS;
}




I just need the new words to appear after i enter the whole of main words,, and not after each word..
Any help??
