LinkedIn "Zip" puzzle

It would be nice to see a coding challenge when you try to create and solve the LinkedIn's puzzle in p5.js (here's a [reference](https://www.linkedin.com/games/zip)).

Follow up challenge: given a solution (that is proved to be unique), how would it be possible to get to the initial map (hence with numbers and walls)?

Start by reviewing the linked LinkedIn Zip reference and defining the scope of the proposed p5.js coding challenge. Clarify whether the work includes only creating and solving puzzles or also reconstructing an initial map from a unique solution. Done means the agreed challenge behavior and follow-up scope are implemented and demonstrated.
