The purpose of this problem is to verify whether the method you are using to read input data is sufficiently fast to handle problems branded with the enormous Input/Output warning. You are expected to be able to process at least 2.5MB of input data per second at runtime.

Input

The input begins with two positive integers n k (n, k<=10⁷). The next n lines of input contain one positive integer t_i, not greater than 10⁹, each.

Output

Write a single integer to output, denoting how many integers t_i are divisible by k.

Sample Input 1

7 3
1
51
966369
7
9
999996
11

Sample Output 1

4

Explanation

The integers divisible by 33 are 51,966369,9,51,966369,9, and 999996999996. Thus, there are 44 integers in total.
