Golf from for everyone

    All with Friday! Following the results of the recent meeting, I want to invite everyone to compete in solving the problem.

    Golf is a sports game in which individual participants or teams compete by driving a small ball into special holes with club strikes, trying to cover the allotted distance in the minimum number of strokes.

    The game I want to invite you to play is also called Golf. Its essence is to solve the problem for the minimum number of characters.

    Domino Challenge: on Github

    Domino is a game in the process of which a chain of knuckles (“bones”, “stones”) is built, touching in half with the same number of points. Thus, each knuckle is characterized by a pair of numbers, no matter in what order.

    Challenge. Find the longest possible ring, which can be made from the list of knuckles offered to you or print 0 if they cannot be looped.

    Input: A string of pairs of numbers from 0 to 6, separated by a space. Each pair is one knuckle.
    Example: 01 11 12 22 31 32
    Data is sent to STDIN: cat data |
    Example of response: 11 12 22 23 31

    You can check the solution’s functionality with the attached test suite, so far only for perl (send your pool requests):
