"... matching pairs..."
By chance I found this and slightly adopted it:
#!/usr/bin/env perl
use strict;
use warnings;
use Data::Dump;
use feature qw(say);
my @s = split //, "AAAA";
my @m = map { $s[$_] . ' ' . $s[ $_ + 1 ] } 0 .. $#s - 1;
dd \@m;
say scalar @m;
__END__
I'm still wondering why it works ;-)
Update: Getting the letters:
dd grep { $_ ne "" } split /[^A]/, q(AAGAATGCCAGTTTGTAAGTACTGACTTTGGAAAA);
