Dear Monks,
I have recently embarked on my journey in Perl and I am already stuck with my first (most likely super trivial problem: I found a code snippet that I want to practice changing, where the example has the following array:
@ranges = ([172,178],[183,189],[201,208]);
and the command:
$input =~ s/(\d+)/(grep {$1 >= $_->[0] && $1 <= $_->[1]} @ranges) ? $s
+ymbol : $1/eg;
So, my problem is, how can I create the
@ranges array in the way it's written in this example? I've been trying several ways, like:
@ranges = ();
push @ranges, "[172,178]";
push @ranges, "[183,189]";
push @ranges, "[201,208]";
but the code does not run (it runs properly using the above snippet, but somehow the array must be written in the form I have specified above, else the
grep command does not work.
Can you help me please?
