Keenan Tims	da25b73eca	day16: use tail recursion unstead of passing mutable state	2023-12-16 11:07:39 -08:00
Keenan Tims	842def62dc	day16: back to elegant recursion now that we track beams ... problem 1 solution was busting the stack, so used an iterative approach, but now that we track lit beams we can bail out early enough not to bust the stack. performance is the same but it's much nicer.	2023-12-15 23:54:22 -08:00
