I notice this solution will get TLE and i make generation file to hack it

main contain this code snippet

string a="";
for (int i = 0; i < 1000000; ++i){
  a+='1';
}
cout<<a<<endl;
cout<<a;

but i got FAIL Input can't contain two or more consecutive spaces, but line 31 (1-based) contains [validator wfval.exe returns exit code 3]

can i know what's the problem in my generator
