Farmer John's cows are on a road trip! The odometer on their car
displays an integer mileage value, starting at X (100 <= X <= 10^18)
miles at the beginning of their trip and ending at Y (X <= Y <= 10^18)
miles at the end of their trip. Whenever the odometer displays an
'interesting' number (including at the start and end of the trip) the
cows will moo. A number is 'interesting' if when you look at all its
digits except for leading zeros, at least half of these should be the
same. For example, the numbers 3223 and 110 are interesting, while
the numbers 97791 and 123 are not.

Help FJ count how many times the cows will moo during the trip.

* Line 1: The first line will contain two integers, X and Y, separated
by a space.

* Line 1: A single integer containing how many times the cows will moo
during the trip.
