Write a program that asks the user to input a speed limit followed by a driver's speed.

Use the following rules to display proper messages.

If the speed is less than the speed limit$,$ it should print $"$OK$."$

For every $5$mph above the speed limit$,$ it should give the driver one penalty point. If there is no penalty, display $"$OK$."$; otherwise, display the total number of penalty points. If the driver gets more than $6$ points, the function should print "License suspended."
