okay, less of a hack :)
## usage example: ## program.pl -cards 5 -holes 3 use strict; use warnings; use feature 'say'; use Getopt::Long; use Algorithm::Combinatorics 'combinations'; main(); exit 0; sub main { GetOptions( 'cards=i' => \my $cards, 'holes=i' => \my $holes ); die "Usage: $0 -c CARDS -h HOLES\n" if !defined($cards) || !defined($holes) || $cards <= 0 || $holes <= 0 || $cards < $holes; $cards -= $holes; my $tot = $cards + $holes - 1; my $combos = combinations( [ 0 .. $tot - 1 ], $cards ); while ( my $combo = $combos->next() ) { my @result = (1) x $holes; for my $i ( 0 .. @$combo - 1 ) { $result[ $combo->[$i] - $i ] += 1; } say join ', ', @result; } }

Title:
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 How to display code and escape characters are good places to start.
