How do you figure? As far as I understand he is trying to solve this kind of
puzzle:
SEND
MORE
+ ————
MONEY
Where every letter is to be replaced by a digit in such a way that the sum
checks out. Sure trying to
solve this by starting with the string: "SEND + MORE == MONEY" and doing
replaces until eval comes up
with true is not very sofisticated but I wouldn't call it shoehorning either.
