Here's a function that implements this logic. You pass it the number of players and the round number and it returns a list of numbers. Each pair of numbers is a matchup for that round. (A pair of say 1,4 means "Player 1 plays Player 4".)

# Function for determining the matchups in a round-robin # tournament round, given the number of players and the # round number. sub matchups { my $players = shift; my $round = shift; # Sanity check the round number if ($round < 1 || $round > $players-1) { return; } my @list = (1, 1+$round .. $players, 2 .. $round); my @pairs; for (0 .. $#list / 2) { push @pairs, $list[$_], $list[$players-1 - $_]; } return @pairs; }
If there are an odd number of players, the last pair will be the same number twice (meaning "Player 4 plays Player 4"), which is essentially a bye.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
