in reply to (Golf) mobile phone numbers -> words

Not a solution, just helping others to solve the problem:

I would assume that the dictionary is already stored as @d. Also, the number to letters translation matrix is stored as a hash of arrays: 

my %a = ( 1 => [],
          2 => [a,b,c],
          3 => [d,e,f],  
          etc... );

This should help everyone start from the same footing.

    I think there is room for creativity here... 
    %d=map{($_,int((-90+ord)/3.14))}"a".."p","r".."y";

      The only critique I have on that is that some phones do have 'q' and 'z' (on the 7 and 9 respectively). While chances are that for the problem at hand, adding q and z won't increase the word set that much, there's still a possiblity of doing so.

      Though I find it rather interesting that PI comes into play, though that's probably a rementent from the rotary phone era.

    You could also store it as an array: 
    my @letters = (
        undef,
        undef,
        ['a', 'b', 'c'],
        ['d', 'e', 'f'],
        ['g', 'h', 'i'],
        ['j', 'k', 'l'],

    etc.

      As it's a Golf, you should use $[=1 or 2 to change array's indice.
      BTW: I don't really understand your problem.

      Update: thanks mischief, for yor explanation.

        The challenge is to write the shortest sub, so changing the indice wouldn't matter.

        The problem is to figure out possible words that you could use instead of your number. Like someone can say "call me on 0602 SEX MAD", and their number would be 0602 739 623, because the letters S E X M A D correspond to the numbers 739 623 on the keypad.
