I submitted the solution to 1367D - Task On The Board during the contest (**Pretest Passed**). Later on, someone hacked it, that's fine.
But after analyzing a bit I found my code wasn't even working correctly for TestCase 1, then how did it pass the pretests.
Here is my submission 83979354, kindly check my output on test1 of testcase1.
I don't have 2 'b's. This shouldn't have passed the checker was wrong itself during the contest.
It must have affected a lot of people as well.
Sorry to say but will this make the contest unrated?
UPD1: As expected my solution is hacked on Testcase 1 itself. The same checker first passes the solution, and later fails the solution on the same Testcase, does that make any sense?
