All modern mobile applications are divided into free and paid. Even a single application developers often release two versions: a paid version without ads and a free version with ads.

Suppose that a paid version of the app costs p (p is an integer) rubles, and the free version of the application contains c ad banners. Each user can be described by two integers: a_i — the number of rubles this user is willing to pay for the paid version of the application, and b_i — the number of banners he is willing to tolerate in the free version.

The behavior of each member shall be considered strictly deterministic:

• if for user i, value b_i is at least c, then he uses the free version,
• otherwise, if value a_i is at least p, then he buys the paid version without advertising,
• otherwise the user simply does not use the application.

Each user of the free version brings the profit of c × w rubles. Each user of the paid version brings the profit of p rubles.

Your task is to help the application developers to select the optimal parameters p and c. Namely, knowing all the characteristics of users, for each value of c from 0 to (max b_i) + 1 you need to determine the maximum profit from the application and the corresponding parameter p.

The first line contains two integers n and w (1 ≤ n ≤ 10⁵; 1 ≤ w ≤ 10⁵) — the number of users and the profit from a single banner. Each of the next n lines contains two integers a_i and b_i (0 ≤ a_i, b_i ≤ 10⁵) — the characteristics of the i-th user.

Print (max b_i) + 2 lines, in the i-th line print two integers: pay — the maximum gained profit at c = i - 1, p (0 ≤ p ≤ 10⁹) — the corresponding optimal app cost. If there are multiple optimal solutions, print any of them.
