OK, this one is pretty easy - but it makes you think and it's a nice break from the day.

Write a program that takes in 3 values: distance(eg. miles), efficiency(eg. miles/gallon), and current fuel(eg. gallons). Your program must give a response (in English) stating whether or not the person has enough fuel to make it on this trip. Now the catch: you cannot use conditionals in your code (if, switch, etc) - no decision logic whatsoever.

Post your solutions, it will be interesting to see what people come up with. (I have solved this and I will post my code after there are some correct responses)

Not sure if this is correct, but here you go... a PHP command line program attached to avoid spoilers.

You want to make the the response a "yes" or "no" type of English response - no numbers.

You are using decision logic there with the regular expressions (looking for the - sign). No conditional expressions whatsoever allowed! Only mathematical computations and outputting strings.

I'll give a hint...

make the output something like:
You will make it.
You will not make it.

I'm not quite sure how you would go about writing this without useing at least one conditional. How do you choose the output??

Have not had time to work this out, perhaps later tonight.
But there may be something in the fact that in logic these two statemens are logically equivalent:

P -> Q (P implies Q, i.e. conditional)
P' | Q ((not P) or Q)

Hmmm ... maybe i am on a tangent but i'll think about that!
