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
Solution
Language – C++
#include<iostream>
using namespace std;
int main() {
int n,k,c=0;
long long int num;
cin>>n>>k;
for(int i=1;i<=n;i++) {
cin>>num;
if(num%k==0)
c++;
}
cout<<c<<endl;
}
