String append actually appends the second string onto first one. So when you did a.append(b) in comparison function then you actually modified the content of string a which you are again using in next line. I would suggest you should use string concatenation (using + operator) so that your a and b do not get modified.

int compare( string a, string b)
{
string s = a+b;
string t = b+a;
return s > t;
}

Also, you forgot to print a newline after each test case :slight_smile:
