Marko is going to write a secret letter to a friend. He thought it is better to encrypt letter so that no other person can read it. After long thought he came up with an encryption scheme which was lame but he thought it will work anyways.

intest - enormous input test

Tue, 24 Mar 2026 00:00:00 +0000

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.
