[Request learning materials] Hall's Marriage Theorem
Hello!
I've seen a couple of scenarios where the intended solution is to use Hall's Marriage Theorem on some weird reduction to solve the problem. These are few and hard to find, so I wanted to ask you for any problems/learning materials regarding this theorem.
One example is IOI-2015/Day1/Teams.
Thank you in advance
