He's just pulling your chain.
I used a matrix, like other people mentioned, and
little logic nodes connected with arrows to show the relationships
to logically solve it. ( Years ago when I first saw it ).
No brute force is required with a matrix approach.
Although I kinda cheated on the last step... I had
two possibilities left without a clue to which was the
correct one, so I just plugged both in to see which worked.
End of problem. Im sure there was a logical clue somehere,
but SOMETIMES brute force is the most efficient method.
Deep Blue beat Kasparov using brute fruce, after years and
years of people working on complex algorithms to beat him.
Guess they finally gave up, and decided a few thousand
processors would do the job just fine

Quote from Gordon Gekko:
hold your horses. i did the same thing anyone else would do with a pencil and a piece of paper. just because i used excel does not mean i did not use logic and just moved things around til they fit. i could explain step by step how i solved it.
