    Return an integer denoting the sum of all numbers in the given range satisfying the constraint.

    Example 1:

    Input: n = 7

    Output: 21

    Explanation: Numbers in the range [1, 7] that are divisible by 3, 5, or 7 are 3, 5, 6, 7. The sum of these numbers is 21.

    Example 2:

    Input: n = 10

    Output: 40

    Explanation: Numbers in the range [1, 10] that are divisible by 3, 5, or 7 are 3, 5, 6, 7, 9, 10. The sum of these numbers is 40.

    Example 3:

    Input: n = 9

    Output: 30

    Explanation: Numbers in the range [1, 9] that are divisible by 3, 5, or 7 are 3, 5, 6, 7, 9. The sum of these numbers is 30.
