OEIS - Fetch values from sequences of the OEIS.
use OEIS; my @list = oeis (45, 10);
Getting tired of all those challenges asking for the first N values of an OEIS sequence. There isn't much to do in such a case then just fetch the numbers from the OEIS.
The OEIS module exports a single function, oeis, which takes two arguments:
OEIS
oeis
The first argument is the sequence number. This can either be the full sequence number (an A or B followed by 6 digits), or just a number. In the latter case, the number is padded with zeros to make it 6 digits long, and an A is prepended.
A
B
The second, optional, argument indicates how many numbers of the sequence we want to return. If not given, the method just returns all the integers listed at the OEIS for the sequence; otherwise, it will be capped by the given amount.
For a very few sequences, if the number of listed integes is less than the given amount, the rest will be calculated.
