charactercount

I have the following Perl script counting the number of Fs and Ts in a string: my $str = "GGGFFEEIIEETTGGG"; my $ft_count = 0; $ft_count++ while($str =~ m/[FT]/g); print "$ft_count\n"; Is there a more concise way to get the count (in other words, to combine line 2 and 3)? my $ft_count = $str =~ tr/FT//; See perlop . If the REPLACEMENTLIST is empty, the SEARCHLIST is replicated. This latter is useful for counting characters in a class … $cnt = $sky =~ tr/*/*/; # count the stars in $sky $cnt = tr/0-9//; # count the digits in $_ Here's a benchmark: use strict; use warnings; use Benchmark qw(

Please tell me what I am doing wrong in both the jQuery and the JavaScript code I have in my contact.js file. $(document).ready(function() { var tel1 =
