When I used this code:
if (q == 0) {
    out.println(fullName);
    return;
}
if (set.add(name)) q--;
I got WA 2.

Then I replaced it by:
set.add(name);
if (set.size() > q) {
    out.println(fullName);
    return;
}
and got AC.

So, can anybody explain me why?
JavaDoc says:
"Returns:
true if this set did not already contain the specified element",
or, in our problem, if this team is the first team of this university.
Can you give me a test where my first solution gets WA, and the second gets AC?

P.S. I got AC WITHOUT any comparing in lowercase!
