Quite happy with the result of today's puzzle! Had to implement my own hacky stack but it was quite doable, did not miss python that much this time around :p

My uhhh very verbal Liberty BASIC solution... I really did miss pre-implemented string- or datastruture manipulation functions available in python more than on the other days. Ended up with 199 lines haha (including some leftover prints and comments)

Day 6 Proof of Correctness
Note also that you can solve this without a complexity dependency on n. Most solutions I have seen, including mine run in time O(tD), where t is the maximum value of a timer, and D the number of generation, requiring O(t) memory. (This is assuming we can do the required arithmetic operations in constant time, and each numbers require a fixed around of memory storage; if the number of fish gets huge, throw in an additional log n in the complexities, where n is the number of fish on the final day).
