Nim
Part 1 is just a sorting problem. Nim's standard library supports sorting with custom compare functions, so I only had to implement cmp() for my custom type and I was done in no time.
To get the star in Part 2 I was generating every possible combination of card hands with Jokers replaced by other cards. It was pretty fast, under a second. Didn't figure out the deterministic method by myself, but coded it after couple hints from Nim Discord people.
Didn't expect an easy challenge for today, but was pleasantly surprised. No weird edge cases, no hidden traps, puzzle text was easy to understand and input parsing is painless.
Total runtime: 1 ms
Puzzle rating: Almost Pefect 9/10
