My solutions to https://typehero.dev/aot-2023 .

Plans

• Study other solutions and see if I can improve mine and review gaps, note differences.

Solutions to study:

https://github.com/TkDodo/aot-2023

• 03: Uses TSomething for longer readable generic type variable names.
• 05: Used ReadonlyArray
• 12: TkDodo's algorithm is simpler.
• 13: Indeed my method was brute-force. I used a combination of addition and recursion to get a full list. I guess the method I thought of was similar to what others came up with. The use of Acc[number] is simpler, and the use of Exclude is cleaner. The use of recursion is restricted to only the Fill, which is simpler and easier to read.
• 14: I've got a cleaner solution here :)
• 16: Predicate<T> extends infer Result as a way to save a variable. Great use of Mapped types to do a search for Santa on the rows then retrieve it via [number], relying on never being not returned in the results. Find column method is the same algorithm.
• 17: This solution is much simpler and cleaner than mine. I can definitely simplify my solution further.
