Paladin,
Wow. That certainly is much neater than my solution. I knew there were likely canned solutions, but it seemed like a cool problem to solve:
#!/usr/bin/perl
use strict;
use warnings;
print "$_\n" for Get_Unique_Random(10 , 3);
sub Get_Unique_Random {
my ($max , $total) = @_;
# Requires error checking obviously
$total ||= 3;
my @return;
while ( @return < $total ) {
my @list = ( 1 .. $max );
for my $seen ( @return ) {
@list = grep { $_ ne $seen } @list;
}
push @return , $list[ (int rand $#list) + 1 ];
}
return wantarray ? @return : \@return;
}
Cheers -
