As with real life, the speed generally doesn't matter as long as you get a working solution and you find it fun. If you find "copy and paste into an LLM and then copy and paste the answer back out" fun, then I suppose you do you.
I didn't realise it was be timed, which is good because I casually set up a new rig to give future puzzles some kind of rig. I used C# which, although probably more wordy than other solutions, did the job and LINQ made light work of the list operations. Ended up with about 6.5 minutes for each one but most of that was refactoring out of pedantry.
