a telephone keypad has letters associated with each number (e.g. 2 = abc, 3 = def); given a passphrase of "fb1" (e.g. one that you might use to log into a bank account), come up with an algorithm that would assemble an array that contains all the different possible letter combinations that, when typed into a telephone dial pad, would be equivalent to the original passphrase.
