What does "monkey patched" mean?

Mᴀʀs Uʟᴛᴏʀ

Monkey patch

A monkey patch is a way for a program to extend or modify supporting system software locally (affecting only the running instance of the program). == Etymology == The term monkey patch seems to have come from an earlier term, guerrilla patch, which referred to changing code sneakily – and possibly incompatibly with other such patches – at runtime. The word guerrilla, homophonous with gorilla (or nearly so), became monkey, possibly to make the patch sound less intimidating. An alternative etymology is that it refers to “monkeying about” with the code (messing with it). The definition of the term...

A: Sandbox for Proposed Challenges

@Sp3000 What about it don't you get?

Sp3000

Suppose A has [QH ... 6H 10H 3H 5H 2H] and B has [KD ... 8D 7D 3D 5D 2D] (top of deck to the right). Does it compare 2H vs 2D, 5H vs 5D, 3H vs 3D then finally 10H vs 7D so A wins and gives all battled cards to B?

Q: Determine the winner of a game of War

The card game War is interesting in that the final outcome is entirely determined by the initial arrangement of the deck, so long as certain rules are followed for the order in which cards are picked up from the playing field and moved to decks. In this challenge, there will only be 2 players, si...

First the top cards are compared. If they're not equal, then 2 more cards are added to each stack from each deck, and the topmost card is compared again. This continues until a player wins the round, at which point they place their stack on top of the loser's stack, flip the entire stack upside-down, and place it on the bottom of their deck.

Reference implementation:

#!/usr/bin/env python3

from collections import deque

p1, p2 = [deque(s) for s in (input(),input())]
print(''.join(p1))
print(''.join(p2))

try:
    while p1 and p2:
        p1s = [p1.popleft()]
        p2s = [p2.popleft()]
        while p1s[-1] == p2s[-1]:
            p1s.append(p1.popleft())
            p2s.append(p2.popleft())
            p1s.append(p1.popleft())
            p2s.append(p2.popleft())
        if p1s[-1] > p2s[-1]:
            p1.extend(p2s+p1s)
        else:
            p2.extend(p1s+p2s)

Sp3000

So stack =/= deck here, and here it would compare 2H vs 2D, 3H vs 3D then 6H vs 8D? (i.e. every second)

Yep

The stacks are the card piles formed by flipping the top card of each deck face-up

@HelkaHomba I would love to be raise

(was confused because I thought "top of the deck" was referring to the previous just-battled top of the deck, rather than the top of the deck after removing the just-battled top of the deck)

It helps to visualize two real people playing the game

This would also be a pretty interesting challenge without the termination/no-ties assumption :P

Anonymous

Yeah, but checking for cycles would make it needlessly complicated IMO

Anonymous

I wanted to make it relatively simple

Anonymous

Though testing for a tie wouldn't be too hard (after every round, check to see if every other card in each of the two decks are equal and the decks are equal size)

Hello

Was watching The Angry Birds Movie. Did anyone see it?

After I saw the trailer, I decided not to watch it

I've heard it's actually pretty good

I'm planning on watching it soon

How's my Sandbox post? meta.codegolf.stackexchange.com/a/9240/47581

Sp3000

Feels like most of the work is just converting to/from spiral coordinates

Also why is queen_spiral(14, 14) -> 0

Bálint

I just got an idea of a very very unproductive SE site

Sherlock9

@Sp3000 Whoops

@Sp3000 Fair enough. Shall I drop it?

Sp3000

Well I'm just wondering what the alternative would be

Sherlock9

The alternative? Also I fixed queen_spiral(14, 14) -> 14

That was a brain fart on my part

Sp3000

As in, if the input was just two pairs of coords (x1, y1), (x2, y2) then the challenge might be too simple (or maybe that's fine, I dunno)

@Bálint Urbit is a bit of a personal server that connects to the Peer to Peer network %ames.
