Hi All! I have the following problem. Created a shuffle function for a deck of cards. When I call the function against an array once, everything looks good. When I execute the function a second time, the results from the first shuffle append to the second. Can somebody tell me why?
Here is the script:
#!/usr/bin/perl
@deck = (card1,card2,card3,card4);
@shuffle1 = shuffle(@deck);
@shuffle2 = shuffle(@shuffle1);
print "@shuffle1\n";
print "@shuffle2\n";
sub shuffle () {
$e = 0;
$b = $#array;
while ($e < $b) {
push(@newdeck, "$array[$e]","$array[$b]");
$e++;
$b--;
}
return @newdeck;
}
