# Enormous Input Test CodeChef Solution

## Problem – Enormous Input Test CodeChef Solution

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 ti, not greater than 109, each.

### Output

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

Input

Output

```7 3
1
51
966369
7
9
999996
11
```
`4`

### Explanation:

The integers divisible by 3 are 51,966369,9, and 999996. Thus, there are 4 integers in total.
