//Exploiting poor testcases and awful ceoi grader used by oj.uz.
//This should be fixed by having the grader have pre-set points
//at the beginning of running instead of creating points in an
//attempt to make it 'worst case scenario' and also using odd n
//testcases. This is probably my least favorite problem ever lol.
