Remove words from string with duplicate chars

i-studio — Tue, 19 Apr 2011 21:25:28 +0000

Imagine that you need to delete words that contain duplicate letters.

The first choice:


my $a = "1asdf 2sdfg 3dfggdf 4sdfrrsdf 5sdfsdf 6dghgyyghf 7fdfgd 8hgggiu";
my @b = split / /, $a;
foreach my $w (@b) {
    next if $w =~ /(.)\1/;
    print $w." ";
}

But we can do it more simple:

$a =~ s/(\b.*?\b)\s(\w+(.)\3\w+)/$1/g;

Example:

$ perl -e 'my $a = "1asdf 2sdfg 3dfggdf 4sdfrrsdf 5sdfsdf 6dghgyyghf 7fdfgd 8hgggiu"; $a =~ s/(\b.*?\b)\s(\w+(.)\3\w+)/$1/g; warn $a'
1asdf 2sdfg 5sdfsdf 7fdfgd at -e line 1.

I fixed the login with livejournal.com OpenID today. It will start working after the next release.

Let’s start!

i-studio — Sat, 22 Jan 2011 12:33:18 +0000

Welcome!

This is a start. I started a blog.

What I am about to write? At the moment it’s about programming (mostly in Perl).
