# DCP-147: Brother's Challange Back to All Problems

Easy Math > Number Theory

Shovon has recently learned about number theory and its amazing properties. Since then, he has been annoying his brother, Badhon with numerous questions about number theory. To calm him down, Badhon gave him a task. He said, "If I gave you a number **N**, can you tell me the numbers below **N** that are divisible by 3 or 5?" Shovon, being a cleaver boy, told his brother, "That's too easy, I can even tell you the summation of these numbers." Badhon agreed. But before he starts asking question to Shovon, he needs a program to verify his answers. Now he has come to you for help. Input: ------ Input will consist of an integer **N (1 ≤ N ≤ 100000)**. Output: ------- Output the required summation. Sample Input ------------ 100 Sample Output ------------- 2318
