Re^2: Yet Another Rosetta Code Problem (Perl, Ruby, Python, Haskell, ...)

Here's a way to "forget" the group...

#!/usr/bin/perl

use strict; # https://perlmonks.org/?node_id=11137799
use warnings;

$_='ZBBBCZZ';

my @list = split ' ', s/(.)\K(?!\1)/ /gr;
use Data::Dump 'dd'; dd "given $_ got", \@list;
[download]

Outputs:

("given ZBBBCZZ got", ["Z", "BBB", "C", "ZZ"])
[download]

And I see pKai is from Erlangen - an easy 216.6 km scenic drive from Darmstadt. :) Nice necropost BTW. Update: Maybe you should try to hire pKai to replace your new Python guy. :)	[reply]

I noticed. Actually our last "real" German Perl Workshop in 2020 ° was there and I'm wondering if I (ever) met him. :) (There was a time where I thought Erlang was named after Erlangen ...) Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery} °) the only in-house/unwired Perl Workshop of 2020 AFAIK! =)	[reply]

No, it's not. The output even shows it is not. ("given ZBBBCZZ got", "Z", "BBB", "C", "ZZ")	[reply]

Oh lord .... you are right! All praise the `/r` flag! :) And let's hope no one will ever stumble over the semipredicate whitespace you inject for splitting ;-) Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]
