Words hidden in my phone number Telephones in the United States (and perhaps some other places) have letters associated with some of the numbers.

2 = A, B, C
3 = D, E, F
4 = G, H, I
5 = J, K, L
6 = M, N, O
7 = P, Q, R, S
8 = T, U, V
9 = W, X, Y, Z


No letters are associated with the number 0 or 1.

Your challenge: Given any phone number in seven-digit or ten-digit format, return English words or phrases into which it could be translated using the code above. Spaces do not matter.

So, for example
873-5377 can be translated to “useless” or “trek-err” and possibly a few others depending on your words list.

For the purposes of this contest,


All digits in the phone number must be used and must be translated into letters. This means that phone numbers containing 0s or 1s can not be translated.
If your operating system or programming environment has a built-in words list (/usr/share/dict/words or the equivalent), go ahead and use it. Otherwise, you can assume that a word list has been downloaded to a convenient directory. However, (a) no-preprocessing of the dictionary to limit it to seven and ten letter words or anything like that, and (b) you have to open the dictionary and load the words yourself; you can’t just pass a variable that contains a list of words.
If your dictionary includes proper nouns, it’s OK to have them in your output.
You can not assume that your input is an integer. The number 213-867-5309 might be input as (213) 867-5409 or 2138675309. Strip all non-numerical characters and make sure what’s left is a seven or ten-digit integer.
Your answer can be a function or a complete program, but no snippets.


FOR EXTRA CREDIT


You may implement a version of the code that replaces rule 1 with a more forgiving test — you may leave up to 2 numbers as numbers while changing all the other numbers to words. If you choose this path, the code must complete a comprehensive search and not do something trivial like leaving the first two numbers as numbers while doing word substitution on the rest. Obviously in this variation, phone numbers with up to two 0s and 1s may be translated.


Using the same test number as above, rule 6 gives us the answers "us-elf-77", "us-ekes-7", and others in addition to the answers above.

SCORING

Shortest code wins, but if you’ve implemented rule 6 you can cut your length in half. I also plan to call out interesting solutions or solutions from verbose languages that might have won if their command names were shorter.

(1) The first line of the code, will replace each number in the input with the corresponding set of possible letters.

þ                                              # Only digits of input.
 "! ! ABC DEF GHI JKL MNO PQRS TUV WXYZ"       # Push keypad letters.
                                        S#     # Split into list and on spaces.
                                          sS   # Split input into digits.
                                            èU # Push indexes of digits and store in X.


(2) The second line of the code, will push every possible dictionary word that is stored in 05AB1E. It accomplishes this by pushing all pairings of the dictionary encrypted characters and converting them to their dictionary stored equivalents. There are 100 unique dictionary characters, and 100*100 unique pairs of them. This means we are getting access to a total of 10,000 words from the 05AB1E dictionary.

(3) The third line of the code, will filter the dictionary by the length of the number of digits in the input.

(4) The fourth line of the code, will filter again the words from the dictionary which match the filter of possible letters outlined by line #1.

(5) The final line of the code, will simply return an empty array provided that the input was not 7 or 10 digits long after parsing.



Using no external libraries/files, this code can detect any word that is in the 05AB1E dictionary. More specifically, if the input is limited to 7 characters the following list:
