A much better shuffle is List's shuffle method. |
|||
<lang zkl>fcn riffle(deck){ |
|||
len,N:=deck.len(),len/2; |
|||
newDeck:=N.pump(List,'wrap(n){ return(Void.Write,deck[n],deck[N+n]) }); |
|||
if(len.isOdd) return(newDeck.append(deck[-1])); |
|||
newDeck |
|||
} |
|||
fcn overHand(deck){ |
|||
len,N,piles:=deck.len(),(0.2*len).toInt(),(len.toFloat()/N).ceil().toInt(); |
|||
piles.pump(List,'wrap(n){ deck[n*N,N] }).reverse().flatten() |
|||
}</lang> |
|||
<lang zkl>riffle( [1..19].walk()).println(); |
|||
overHand([1..19].walk()).println(); |
|||
[1..19].walk().shuffle().println();</lang> |
