The twenty years of waiting "paid off".
Yes. Indeed it has. Check out this Raku code of mine which is a solution for this years day 14. Any experienced programmer should be able to make sense of, and mostly understand it after spending 2 hours with the docs. I doubt the same is true for any perl implementation of similar brevity.
my ( \o, \r ) = .head.comb.List, .tail.comb( /\w/ ).map( -> $a, $b, $c { "$a$b" => [ "$a$c", "$c$b" + ] } ).Hash with cache $*IN.slurp.split: "\n\n"; sub day14( \n ) { my %d = o.rotor( 2 => -1 ).join.Bag; %d = [(+)]{ r.{.key} => .value }) for ^n; .Bag.values.minmax.elems - 1 with ( o.tail => 1, |%d ).map: { .key.comb[0] => .value }; } say day14 10|40;


You can lead your users to water, but alas, you cannot drown them.

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.
