I haven't been in these forums for a while... I've been learning much about Linux and about Perl and PHP :-)

I do know a lot of C, but not much C++, and I found a cool website that has an online judge and I've been working on some problems there.

Enormous Input Test

My program failed twice because of exceeded time limit. Here is my code:Code: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

What would be a better way to read all the input faster? I also tried reading from cin and testing for division on the same loop, but that was not fast enough either.Code:#include <iostream> using namespace std; int main() { long n, k, count = 0; cin >> n >> k; long *ti = new long[n]; for(int i = 0; i < n; i++) { cin >> ti[i]; } for(int i = 0; i < n; i++) { if(ti[i] % k == 0) count++; } cout << count; }

Thanks!
