NAME

Math::NumSeq::BaumSweet -- Baum-Sweet sequence

SYNOPSIS

 use Math::NumSeq::BaumSweet;
 my $seq = Math::NumSeq::BaumSweet->new;
 my ($i, $value) = $seq->next;

DESCRIPTION

The Baum-Sweet sequence numbers 1,1,0,1,1,0,0,1,0,1,0,0,etc, being 1 if the index i contains no odd-length run of 0 bits, or 0 if it does.

FUNCTIONS

See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.

$seq = Math::NumSeq::BaumSweet->new ()

Create and return a new sequence object.

$value = $seq->ith($i)

Return the $i'th BaumSweet number, ie. 1 or 0 according to whether $i is without or with an odd-length run of 0 bits.

$bool = $seq->pred($value)

Return true if $value occurs in the sequence, which simply means 0 or 1.
