Welcome to the third competitive contest of the year!

You have 40 minutes to solve three problems of increasing difficulty. Each problem is worth a total of ~100~ points. Each problem will have many opportunities for partial points, so you should go for these if you cannot solve a problem fully!
These problems will revolve around the topics we will cover next week (Graph Theory). It's perfectly fine if you don't know what that is – this is a diagnostic contest.

Good luck!
