Well, we don't really have a challenge like this yet, so here we go.
Consider this 3 x 3 grid of rectangles:
How many rectangles are there? Well, counting visually, we can see that there are actually 36 rectangles, including the entire plane itself, which are all shown in the animated GIF bel...
Write a VIC cipher encoder
code-golfcryptography
The VIC cipher is one of the most complicated pencil and paper ciphers ever devised. Used in the 1950s by Soviet spy Reino Häyhänen, codenamed "VICTOR", its main principle is security through obfuscation; a lot of obfuscation.
Your task is to wr...

In computing, memoization is an optimization technique used primarily to speed up computer programs by storing the results of expensive function calls and returning the cached result when the same inputs occur again. Memoization has also been used in other contexts (and for purposes other than speed gains), such as in simple mutually recursive descent parsing in a general top-down parsing algorithm that accommodates ambiguity and left recursion in polynomial time and space. Although related to caching, memoization refers to a specific case of this optimization, distinguishing it from forms of caching...

Plumber, Python
Plumber is all about flushes. Plumber also prioritises higher value cards (meaning he can sometimes get straight flushes, especially royal ones (should they occur).) Plumber is pretty much messed if he doesn't get a flush, except that he might be lucky enough for a straight. Plum...

LuckyBot, Python
Pairbot invited his buddy Luckybot, who sprang for the chance. Luckybot had watched a lot of fictional poker, and reckoned he'd figured out the secret to poker: luck. Everyone knows the real pros (James Bond, for example) really rely and getting good hands, not skill. Hence, he ...
Your task is to assemble the integers from 1 to N (given as input) into a rectangle of width W and height H (also given as input). Individual numbers may be rotated by any multiple of 90 degrees.
Here is an example. Say your input is (N, W, H) = (12, 5, 3). One possible solution is:
