NAME

6       Math::NumSeq::MaxDigitCount -- maximum count of a given digit in any
7       radix
8

SYNOPSIS

10        use Math::NumSeq::MaxDigitCount;
11        my $seq = Math::NumSeq::MaxDigitCount->new (values_type => 'count');
12        my ($i, $value) = $seq->next;
13

DESCRIPTION

15       This is the maximum count of a given digit which occurs when i is
16       written in any radix.  The default digit is 0.
17
18           0, 1, 1, 2, 1, 1, 1, 3, 2, 2, 1, 2, 1, 1, 1, 4, 3, 3, 2, ...
19           starting i=1
20
21       For example i=15 is 1 because 15 = ternary "120" which has 1 zero, and
22       no other base has more than that.  i is "10" in base i itself so
23       there's always at least 1 zero, after i=1.
24
25   Radix
26       Option "values_type => 'radix'" gives the radix where the maximum
27       occurs,
28
29           # values_type => "radix"
30           2, 2, 3, 2, 2, 2, 7, 2, 2, 2, 2, 2, 2, 2, 3, 2, 2, 2, 2, ...
31
32       If the maximum count occurs in more than one radix the value is the
33       smallest where it occurs.  i=1 has no zeros in any radix and the return
34       is 2 for binary since the count 0 occurs in that radix.
35
36   Digit
37       Option "digit => $n" selects another digit to count, for example
38
39           # digit => 1
40           1, 1, 2, 2, 2, 2, 3, 2, 2, 2, 3, 2, 3, 3, 4, 2, 2, 2, 3, ...
41
42       For example at i=7 the count is 3 since 7 in binary is "111" with 3
43       digit 1s.

FUNCTIONS

46       See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence
47       classes.
48
49       "$seq = Math::NumSeq::MaxDigitCount->new ()"
50       "$seq = Math::NumSeq::MaxDigitCount->new (digit => $d, values_type =>
51       $str)"
52           Create and return a new sequence object.
53
54   Random Access
55       "$value = $seq->ith($i)"
56           Return the count or radix for the selected digit when $i is written
57           in any radix.
58
59       "$bool = $seq->pred($value)"
60           Return true if $value occurs in the sequence.  This simply means
61           $value an integer, but excluding 0 when seeking digit=1, or
62           excluding 1 when seeking the radix.
