Talk:Poker hand analyser
Hi, just some suggestions on the task. (Nice one by the way):
- You might ask people to show their output on this page.
- You might want to flesh out the examples so that there is an example of each type of hand

- I made those changes so Perl 6 will need those (slight), updates. --Paddy3118 (talk) 17:23, 10 December 2013 (UTC)
Another example to add would be a bicycle (to compliment the royal flush) to show that an ace can be used as two different values.
A bicycle (or bike) is a straight consisting of: ace, deuce, trey, 4, and a 5 (the lowest straight possible). -- Gerard Schildberger (talk) 05:40, 12 December 2013 (UTC)
I would like the allowing of expanding invalid responses with (possibly, say)
- invalid --- the reason for invalid flagging here.

In the task's preamble, it says that Each input card has two characters indicating face and suit, but then goes on to show a 10 for a pip (which is two characters).
I suggest that program accept both 10 and a T (and a t).
Also, all pips (on every card deck that I remember) use capital letters for (lettered) pips: A (ace), J (jack), Q (queen), and K (for king). Of course, their lowercase versions should also be accepted. Jokers may or may not be capitalized, but most decks seem to use capital letters. -- Gerard Schildberger (talk) 20:47, 20 December 2013 (UTC)
Amend the question to "Which of these two poker hands wins?". The present analysis, which classifies hands into a coarse ranking, is inadequate for playing the game.
extra credit suggestion
It would be real interesting to program (for extra credit) adding two jokers to the deck, adding a few complications:
- duplicates would be allowed (for jokers only)
- five-of-a-kind would be the highest hand

Thanks Gerard, have added Jokers
--Dwarring (talk) 01:20, 13 December 2013 (UTC)
- But their doesn't seem to be an explanation of the action of jokers? --Paddy3118 (talk) 09:32, 13 December 2013 (UTC)
It's a good thing I didn't mention bugs or wild cards --- or playing with more than five cards per hand (as in some stud poker games).
Bugs are jokers than can represent:
- any generic (non-specific) ace
- any card in a flush or straight (that isn't already in that hand)
Bugs (as in a type of jokers) are easy to program for when analyzing poker hands.
I once played a stud poker game with (all) red cards wild.
I'm still trying to figure out the programming required to support analyzing poker hands where there're more wild cards than non-wild cards (in addition to the jokers, of course). Figuring out if there is a straight with three wild cards is daunting, especially when playing something like 7-card stud. -- Gerard Schildberger (talk) 07:28, 13 December 2013 (UTC)
Gerard, I've taken you extra credit example as sample input. Thanks! Also added a few two joker test cases (sorry to move the goal-posts!)
Also, I notice that a "t♣" has crept into you v2 and v3 tests, as in: q♣ t♣ 7♣ 6♣ 4♣
- Yes, I wanted to show that the REXX program example could handle a t as well as a 10. -- Gerard Schildberger (talk) 21:27, 20 December 2013 (UTC)
ok, that makes sense --Dwarring (talk) 21:23, 20 December 2013 (UTC)
@Tipon - Nice work with the Prolog example.
As a point of Trivia the 'Poker Hand Analyser' task was originally given to us as an assignment, by the lecturer in a 3rd year computer science Software Engineering class. That was a good few years ago.
