This month's challenge is about IBM's InterConnect 2016 conference.
Assign each letter a different digit such that the following mathematical equations would be correct (** denotes exponentiation):
a**connect = c (mod inter)
a**connect = a**toe (mod at)
a**connect = a**toe (mod cm)
n**i = ban
Hint: By guessing a little, this can almost be entirely solved without using a computer.
For a bonus '*', what is the connection of the solution to "XCF MODULE ID FILTER NOT ACCEPTED"?
Update (04/02):
- mod is modulo operation. I.e. x=y(mod z) means that x and y has the same remainder when divided by z. Different letters should be assigned to different digits.
We will post the names of those who submit a correct, original solution! If you don't want your name posted then please include such a statement in your submission!
We invite visitors to our website to submit an elegant solution. Send your submission to the ponder@il.ibm.com.
