Problem Overview: 
You and your friends decided to have some fun and went to a night club where there is a nice dance floor, made of colour LED tiles.
Each time a person steps on a dance floor tile, that tile changes its colour.
For the first song of the night, your group will try to make an impressive performance, following a pre-determined choreography and leaving, in the end, the dance floor as "pretty" as possible.

Here is an example solution for seed = 7. The white arrows indicate the next choreography position for each dancer.

Hope to see most of you compete! All the best!
