# Display the result of doing 8 perfect shuffles of a deck of cards

## Explanation

A perfect shuffle is where a deck of cards is split exactly in half and the cards from each pile are alternately interleaved. The original bottom cards and the original top card must be preserved after a perfect shuffle.

After 8 perfect shuffles, a standard 52 card deck returns to its original order.

## Challenge

Write a programs that displays the state of a deck of cards as it goes through 8 consecutive perfect shuffles. You may use any human readable-representation of a deck, provided that it displays the number and suit of each card in the deck in sequential order. It must display a representation of all of the cards, for all nine states.

This is code golf, so the shortest solution wins.

Whilst not an exact duplicate, this is essentially about half of the task from Mix the nuts (at least as implemented by the current answers). – Peter Taylor Jul 4 '12 at 20:35
Is the starting order of the cards important? – chron Jul 5 '12 at 2:49
@chron No, the cards can start out in any order. – Peter Olson Jul 5 '12 at 6:35

 +1. `[r,'10'][r>"Q"]` is nifty. I don't think you need backticks around the `10`. Quotes would do fine. – Steven Rumbalski Jul 6 '12 at 15:04 @StevenRumbalski, I used backticks for the lulz. Quotes take the same amount of space. – boothby Jul 6 '12 at 15:31 If it were allowable (it isn't) to have the results in reverse order, this would work: `exec'print d;d=d[::2]+d[1::2];'*9`. – Steven Rumbalski Jul 6 '12 at 15:32 Shame to me. I've forgot about `sum`. – Ev_genus Jul 6 '12 at 19:10

Symbols instead of strings will save you 2 characters `a=(0..51).map{|i|:A23456789TJQK[i/4]+:SCDH[i%4]}` – Artem Ice Jul 15 '12 at 13:49
@ArtemIce Good call, for some reason I thought I had tried that unsuccessfully already. Thanks for the tip! – chron Jul 15 '12 at 23:35
You are welcome! One more idea is that we can use `pop` instead of `slice!` and save 6 characters. `9.times{p a;a=a.zip(a.pop 26).flatten}` – Artem Ice Jul 19 '12 at 3:58

### Python3, 180 179

``````from itertools import*;i=list(map("".join,product("A23456789XJQK","SCDH")));exec('print(",".join(i).replace("X","10"));i=list(chain(*zip(islice(i,0,26,1),islice(i,26,52,1))));'*8)
``````

### Native Format 151

``````from itertools import*;i=list(map("".join,product("A23456789TJQK","SCDH")));exec('print(i);i=list(chain(*zip(islice(i,0,26,1),islice(i,26,52,1))));'*8)
``````

Output is like in Ruby version.

I think you can save a char by dropping the space between `import` and `*`: ideone.com/kQTbs – w0lf Jul 5 '12 at 8:25
If you use 2.x, you should be able to drop the first list(), since map() returns a list not a generator. – Joel Cornett Jul 6 '12 at 7:17

Since the cards can start in any order, and since gcd(13, 4) = 1, you can replace `{...}%` by `4*`. – Peter Taylor Jul 6 '12 at 17:22
@PeterTaylor Thank you. Didn't read that "in any order" comment. – Howard Jul 6 '12 at 19:24

### Perl, 91 chars

Any suggestions on a more concise way of building the initial deck? My approach uses 2 substitutions to build `\$_` and then a global match in list context to initialize `@_`.

The shuffling is then done by repeatedly `splice`ing `@_` onto `@a` and interleaving the two lists with `map` back into `@_`.

``````s//A23456789TJQK/,s/(.)/\$1S\$1C\$1D\$1H/g,@_=/../g;say@_=map{shift@_,\$_}@a=splice@_,26for 0..8
``````
-

## APL (42)

``````{↑{⍉2 26⍴⍵}⍣⍵,'A23456789TJQK'∘.,'SCDH'}¨⍳9
``````

Output is top-down instead of left-right (but it's still human readable so I guess it's not against the rules).

Output:

# Mathematica 131129120114100 86 chars

With help from Mr.Wizard:

``````NestList[Riffle @@ #~Partition~26 &, # <> "" & /@ Tuples@Characters@
{"A23456789TJQK", "HDCS"}, 8]
``````

Output:

 MrWizard suggests reducing this to 86 chars as `NestList[Riffle@@#~Partition~26&,#<>""&/@Tuples@Characters@{"A23456789TJQK","HD‌​CS"},8]` – Peter Taylor Jul 28 '12 at 20:45 I did. Very nice streamlining. I especially liked the trick to reduce `StringJoin`. – David Carraher Jul 28 '12 at 22:20
