Re: split chars in string

Why? Perl has very good string handling that generally works much faster on strings than any code that deals with characters one at a time. Tell us what you want to do and we can probably show you a Perlish way to achieve your end that runs much faster than dealing a character at a time.

True laziness is hard work

How about sorting an array of words by the second character of every word? Can that be achieved without splitting the words into characters?	[reply]

`#!/usr/bin/perl use strict; use warnings; use 5.010; chomp( my @words = <DATA> ); @words = sort { substr( $a, 1, 1 ) cmp substr( $b, 1, 1 ) } @words; say for @words; __DATA__ How about sorting an array of words by the second character every word` [download]	[reply] [d/l]

Just look at the second character. `my @sorted_by_second = map { $_->[0] } sort { $a->[1] cmp $b->[1] } map { [$_, substr($_,1,1)] } @unsorted;` [download]	[reply] [d/l]
