Write a program that is given two integers representing a speed limit and driving speed in miles per hour $($mph$)$ and outputs the traffic ticket amount.

Driving $10$ mph under the speed limit $($or slower$)$ receives a $$50$ ticket. Driving $6-20$ mph over the speed limit receives a $$75$ ticket. Driving $21-40$ mph over the speed limit receives a $$150$ ticket. Driving faster than $40$ mph over the speed limit receives a $$300$ ticket. Otherwise, no ticket is received.

Ex: If the input is:

$3545$

the output is:

$75$

Ex: If the input is:

$3526$

the output is:

$0$
