Challenge 29: Table Tennis Tournament
Level: Medium

Description: You work for a Berlin startup and it's Friday night. A table tennis tournament with your colleagues is due! The following problem comes up: how to randomly split all your co-workers in random teams of two players, and then randomly define the direct elimination matches as a dendrogram? Hint: You can use the Hierarchical Cluster Assigner in this challenge.
