Math::NumSeq::BaumSweet -- Baum-Sweet sequence
use Math::NumSeq::BaumSweet; my $seq = Math::NumSeq::BaumSweet->new; my ($i, $value) = $seq->next;
The Baum-Sweet sequence
1, 1, 0, 1, 1, 0, 0, 1, 0, 1, 0, 0, ... starting i=0
where each value is 1 if the index i contains no odd-length run of 0-bits, or 0 if it does.
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)
$i'th BaumSweet number, ie. 1 or 0 according to whether
$iis without or with an odd-length run of 0-bits.
$bool = $seq->pred($value)
Return true if
$valueoccurs in the sequence, which simply means 0 or 1.
