I have avoided looking at solutions to the Day 10 puzzle because the kittens would then demand something different and that makes the problem even harder. For some reason it looked like
https://adventofcode.com/2015/day/22
puzzle 22 from 2015 so I tried breadth first search using the same heap structure in Scratchy's code except translated to Go.
After struggling with the fact that Go doesn't allow a map with a byte slice for the key I switched to storing vectors of 8-bit numbers in strings.
My code easily solved the test data but went into swap on the real puzzle. Scratchy claims the garbage collector is on holiday due to it being Christmas, but I think it might be more than that.
Purr purred that a singular-value decomposition is purrfect for minimal solutions to linear algebra problems but Shy shyly mewed it's not allowed to push a button a non-integer number of times.
