Sum Divisible by Three and Five

You are given a list of integers. Your task is to calculate the sum of numbers that are divisible by both 3 and 5. In other words, you must sum all integers from the input that satisfy the condition:

\(x \text{ is divisible by } 15\)

If there are no such numbers, output 0.

inputFormat

The input is given in two lines.

The first line contains a single integer \(N\) which represents the number of integers in the list.

The second line contains \(N\) space-separated integers.

outputFormat

Output a single integer which is the sum of all numbers that are divisible by both 3 and 5 (i.e. divisible by 15).
