Sum of multiples of 3 and 5

Note

The following problem was inspired by Problem 1 at Project Euler.

If you list all the natural numbers below 10 that are multiples of 3 or 5, you get 3, 5, 6, and 9. The sum of these multiples is 23. Define a function according to the following definition:

sum_of_multiples_of_3_and_5(n)

Return the sum of all multiples of 3 and 5 below n.

Parameters:n (int) – The number up to which the sum of multiples of 3 and 5 is computed.
Returns:The sum of all multiples of 3 and 5 up to n.
Return type:int
