15
16 1, 1, 0, 1, 1, 0, 0, 1, 0, 1, 0, 0, ...
17 starting i=0
18
19 where each value is 1 if the index i written in binary contains no odd-
20 length run of 0-bits, or 0 if it does.
21
23 See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence
24 classes.
25
26 "$seq = Math::NumSeq::BaumSweet->new ()"
27 Create and return a new sequence object.
28
29 Random Access
30 "$value = $seq->ith($i)"
31 Return the $i'th BaumSweet number, ie. 1 or 0 according to whether
32 $i is without or with an odd-length run of 0-bits.
33
34 "$bool = $seq->pred($value)"
35 Return true if $value occurs in the sequence, which simply means 0
36 or 1.
