In a certain country, there are N denominations of coins in circulation, including the 1-cent coin. Additionally, there’s a bill whose value of K cents is known to exceed any of the coins. There’s a coin collector who wants to collect a specimen of each denomination of coins. He already has a few coins at home, but currently he only carries one K-cent bill in his wallet. He’s in a shop where there are items sold at all prices less than K cents (1 cent, 2 cents, 3 cents, … , K í 1 cents). In this shop, the change is given using the following algorithm:
The coin collector buys one item, paying with his K-cent bill.
Your task is to write a program that determines:
The first line of the input file contains the integers N (1 ≤ N ≤ 500 000) and K (2 ≤ K ≤ 1 000 000 000). The following N lines describe the coins in circulation. The (i + 1)-th line contains the integers ci (1 ≤ ci < K) and di, where ci is the value (in cents) of the coin, and di is 1, if the collector already has this coin, or 0, if he does not. The coins are given in the increasing order of values, that is, c1 < c2 < … < cN. The first coin is known to be the 1-cent coin, that is, c1 = 1.
The first line of the output file should contain a single integer — the maximal number of denominations that the collector does not yet have, but could acquire with a single purchase. The second line of the output file should also contain a single integer — the maximal price of the item to buy so that the change given would include the maximal number of new denominations, as declared on the first line.
