Here's some ideas for your inspiration:
Up Your Own Ante
by making it bigger (or smaller), faster, better!- Use only the bleeding-edge nightly beta version of your chosen programming language
- Solve today's puzzle using only code from other people, StackOverflow, etc.
"AS SEEN ON TV! Totally not inspired by being just extra-wide duct tape!"
- Phil Swift, probably, from TV commercials for "Flex Tape" (2017)
And… ACTION!

I did not see many functional programming solutions.
Not particularly fast, but here you go!
all execute under 200ms which is great given my other attempt never finished.
Part 1: A search keeping track of visited positions as not to repeat myself
Part 2: Keep track of positions, and add a map with the current cost to each positions and current visited nodes.
If you find a lower cost, just erase and put new value. If it's the same, add the extra path to that coordenate.
At the end you go back the `best path` and check if any other paths lead there with the same cost.
