And MINDSUM's solution was basically brute Force. Tho the challenge problem is one of my all time favorite challenge problems, unfortunately it had to have the issue during the contest.

Would have loved to see such a comment after contest/not-during-live-contest.

@vijju123 Why? It's better to point it out during the contest, so something can be done during the contest. Of course it would be the best if the tests were strong enough at the start of the contest...

Well...the reason is because, more often than not, the TCs wont be updated if its past a few days from start as many people "leave" the contest after solving those problems.

And it just encourages more people to try heuristic/non-optimal solutions to pass. Thats the main concern. Perhaps pm it or convey via private means.
