Enormous Input Test - CodeChef Solution in C | AskTheCode

CodeChef Practice Problem Solution | C Programming | Ask The Code

---

Problem:

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.

Example

Input:
7 3
1
51
966369
7
9
999996
11

Output:
4

Code:

#include <stdio.h>

int main() {

// Read the input n, k

int n, k;

scanf("%d %d", &n, &k);

// ans denotes number of integers n divisible by k

int ans = 0;

for (int i = 0; i < n; i++) {

int t;

scanf("%d", &t);

if (t % k == 0) {

ans++;

}

}

// Print the ans.

printf("%d\n", ans);

return 0;

}
