Write a function for checking the speed of drivers. This function should have one parameter: speed.

• If speed is less than 70, it should print "OK".
• Otherwise, for every 5 km above the speed limit (70), it should give the driver one demerit point. Calculate and print the total number of demerit points at the end. For example, if the speed is 80, it should print: "Demerit Points: 2".
• If the driver gets more than 12 demerit points, the function should print: "License suspended".

Data plays a very important role in the development and operation of AI. The performances and accuracy of AI models can be considerably impacted by the quantity, quality, and relevance of the data used. Why is data important in AI-based recommendation systems?

Write a function that returns the sum of multiples of 3 and 5 between 0 and limit (parameter). For example, if the limit is 20, it should return the sum of 3, 5, 6, 9, 10, 12, 15, 18, 20.
