    Recursive Programming Brainteaser

    Substitue a number for each character so that when you add the first *word* to the second *word* you get the third *word* as the result.

    ...DONALD
    .+GERALD
    ..-------
    ...ROBERT

    there is only one answer (that I know of) out of a million possibilities. I solved it by brute force on the same day that my mathematician friend did, but forget the answer.

    I have a few hints in case anyone wants them.

    T = an even number
    You can carry the one to the left
    Each character is a different digit
    Digits used are 0-9

    (can't left justify leading spaces.)

    answer is in format
    111111+222222=333333
    dddddd+ccccccc=ffffff

    Have fun
