hailstone

This folder contains an implementation of the Hailstone sequence and it was coded for a contribution to the Rosetta Stone website. For more information see:

http://rosettacode.org/wiki/Hailstone_sequence

http://en.wikipedia.org/wiki/Collatz_conjecture

Print Logtalk, Prolog backend, and kernel versions (if running as a notebook):

%versions

Load the example:

logtalk_load(hailstone(loader)).

Generating a sequence:

hailstone::generate_sequence(10, Sequence).

hailstone::write_sequence(10).

Calculating the length of a sequence:

hailstone::sequence_length(27, Length).

Finding the longest sequence in an interval:

hailstone::longest_sequence(1, 100000, N, Length).
