Hello Codeforces Community!

Today I have studied the problem of finding the minimum spanning tree in a directed graph.
This problem is solved using the two Chinese algorithm (Chu-Liu / Edmonds' algorithm). You can read more about this algorithm in Russian using google translator in Oleg Davydov's blog A little about minimal spanning trees, in the ITMO wiki, here, AlgoCode Wiki. In English you can read in detail: Wikipedia, Tarjan's notes, Uri Zwick's detailed post.

I want to practice solving problems on this topic, but while searching I found very few problems.
Let's create a Codeforces sheet from tasks on this topic! Please help me with this! Share with the problem if you have solved on this topic.
