Dear Monks,
I wanted to simulate drawing random numbers from a bag of numbers containing N numbers. And so did I code it as follows (N=10 for this example, I do not put the drawn number back into the bag):
#!/usr/bin/perl -w
use strict;
my $x;
my $i;
my @my_bag;
@my_bag = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
$i = @my_bag + 1;
while (@my_bag > 0) {
$x = int(rand($i));
$x = $x > 0 ? $x - 1 : $x;
print splice(@my_bag, $x, 1) . "\n";
$i--;
}
I'd be glad indeed if experienced Perl monks could review my code. Is there a BETTER way to write this simulation? A faster way, a more elegant (or maybe more obfuscated ;-) one?
Maybe what I did can also be called "shuffling an array", am I wrong? Any other ways to accomplish the same effect? Broaden my vision and enlighten me :)
