Last problem, my car's odometer hit 56789. It's coming up on 111111 now, which (barring a major miracle) will be the last binary number to ever show up on the odometer. You will be given two numbers - an odometer reading, and a number base. Calculate the number of miles your car will need to travel in order to show the next number that is valid in that base.

You're *very* close with this one. Remember that r is input as a double, not a string.
