"""
# Multiples of 3, 4, 7

If we list all positive integers 10 or below that are multiples of
3, 4, or 7 we get: [3, 4, 6, 7, 8, 9]. The sum of the list is 37.

Given a positive integer n, return the sum of all numbers
less than or equal to n that are multiples of 3, 4, or 7.

Example 1
Input

n = 7
Output

20
Explanation

The solution includes [3, 4, 6, 7] and its sum is 20.
