[Kc] Shuffling a deck of cards...

[Emmanuel Mejias]

okay...tweaked s'more...couldn't get it to print out 5, so let's hope he's
okay with six.

#!/usr/bin/perl -w

@mydeck = ("A H","2 H","3 H","4 H","5 H","6 H","7 H","8 H",
                 "9 H","10 H","J H","Q H","K H",
                 "A D","2 D","3 D","4 D","5 D","6 D","7 D","8 D",
                 "9 D","10 D","J D","Q D","K D",
                 "A C","2 C","3 C","4 C","5 C","6 C","7 C","8 C",
                 "9 C","10 C","J C","Q C","K C",
                 "A S","2 S","3 S","4 S","5 S","6 S","7 S","8 S",
                 "9 S","10 S","J S","Q S","K S");
@top5 = ();
my $x = 0;
while ($x <= 2){
  push (@top5, shift(@mydeck));
  push (@top5, pop(@mydeck));
  $x++;
}
foreach $card (@top5){
  print "$card\n";
}
