#WEEKLY 20 — Multiplication Tables (in LOLCODE!)
fuzzyastrocat (788)

So this week, I decided to make things hard on myself and use an esoteric language. I chose LOLCODE since I've never used it before, and it seems pretty popular.

Little did I know, LOLCODE has no support for lists.

So, this weekly became quite a challenge — how can I solve a problem which requires some sort of list-like data structure to solve (to implement a uniqueness check) with a system that has no lists.

Well, my solution was to realize that what I just said was a lie. There are lists in LOLCODE — yarns (or, as boring normal programmers call them, strings).

So my task became a) encoding a list of numbers in a string,and b) figuring out how to compare a number to all the numbers in that "list", and check if there is a match.

These things probably don't sound too hard, but this is an esoteric language so of course it was difficult. The first goal I accomplished by giving each number an arbitrary precision — 10 digits (which seems big enough that you won't run out of space for something like this challenge while keeping the performance modest). I could then simply pad each number up to 10 digits with leading zeroes, and it becomes possible to get any number out of the list. The next goal was not as easy, but through a lot of loops and fun names like LAZERPOINTER and DIJIT I managed to make it work.

So here it is, a bunch of unreadable code that sounds like your cat wrote it, complete with LOLspeak prompts. It doesn't look like much, but don't assume the complexity of an esoteric program based on its size :D

Note 1: Don't give it big numbers, due to the obvious performance downsides of this approach it will get really laggy. Anything over 20x20 starts to get laggy, so I'd keep it around that range at most. (If you're wondering, under no circumstances put anything greater than 99999x99999 — it will max out the 10 digit limit and be frozen forever!)

Note 2: If nothing shows up at first, re-run the program. It appears that sometimes repl's lolcode interpreter doesn't run the first time.

@fuzzyastrocat gotcha! hmm don't have school tmr, so time to code until 12pm!
