da25b73eca day16: use tail recursion unstead of passing mutable state 2023-12-16 11:07:39 -08:00
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.
