Two days ago, one of my friends (Danylo99) told me about a cool problem from a recent SIT contest. The goal was to find a nontrivial cycle that visits all cells on a 2D grid with even sides.

I thought it would be interesting to visualize the results.

Here is a slightly larger one. If anyone knows other approaches, please share :)

By the way, I also made a video of what's going on inside the algorithm.

Hope you all have a great day!

• How to never give up?

• How to be more confident?

• How to fight fear?

• How to keep the fire inside burning?

I believe that anyone is familiar with those problems and that it is better to talk about it instead of hiding it inside. Share some advice in comments.
