How this contribute get approved?

This day I face on someone contributing to the Clash of Code game, but this is a mess! Two measly lines of code that tell me absolutely nothing! Input and output completely disregarding the guidelines from Codingame! And don’t even get me started on the lack of constraints! How the heck did this contribution get approved?! This is infuriating!

I’m afraid there’ll always be some approvers who don’t do a good review job before they approve contributions. Let’s hope they aren’t the majority…
