Array population

hotshot has asked for the wisdom of the Perl Monks concerning the following question:

Hello fellow monks!

I have a $number variable, and a $string, what is the fastest way to create a list of size $number that holds $string in each list entry? for example:

$number = 4;
$string = 'hello';

# I want to get the list:
@list = qw(hello hello hello hello);
[download]

Thanks

Hotshot

I have a $number variable, and a $string, what is the fastest way to create a list of size $number that holds $string in each list entry? Why by using the repetition operator in a list context of course `my $number = 4; my $string = 'hello'; my @list = ($string) x $number; print @list; __output__ hellohellohellohello` [download] See. the Multiplicative Operators section of `perlop` for more info on the repetition operator.

my $number = 4; my $string = "hello"; my @array = ($string) x 4; Sorry, replace '4' with $number...oops	[reply]
