Hi all,

I read Algorithm for "Incrementing" strings and tried to solve the problem for learning - following the recommendation by tye to use Math::Fleximal.

The specs as provided by ibm1620:

$val = 'BB';
incr($val);  ==> 'BC'

$val = 'BZ';
incr($val);  ==> 'CB';

$val = 'ZZ';
incr($val)  ==> 'BBB';

I think that "ZZ" should be incremented to "CBB".

I tried this:

#!/usr/bin/env perl

use strict;
use warnings;
use Math::Fleximal;
# use Data::Dump;
use feature qw (say);

my @consonants = qw (B C D F G H J K L M N P Q R S T V X Y Z);

my $number = Math::Fleximal->new( "BB", \@consonants );

say $number->to_str();
say $number->base_10();

$number = $number->add("C");

say $number->to_str();
say $number->base_10();

say qq(--);

$number = $number->set_value("BZ");

say $number->to_str();
say $number->base_10();

$number = $number->add("C");
say $number->to_str();
say $number->base_10();

say qq(--);

$number = $number->set_value("ZZ");

say $number->to_str();
say $number->base_10();

$number = $number->add("C");
say $number->to_str();
say $number->base_10();

__END__

Seems like it works as designed (or i hope so).

But in the solutions provided by other monks "ZZ" is incremented to "BBB".

What do i miss?

Update: Thank you very much to all who helped.

Update2: Reset state to [UNSOLVED]

Update3: Set state to [SOLVED]. Thanks again to all for help and patience.

Thank you very much for any hint and best regards, Karl

P.S.: Sorry, i'm pretty bad in even essential math.
