#### 1236. G. Buying in Bulk

#### Description

To encourage customers to shop more, some stores charge lower prices if you buy multiples of an item. For example, if you buy one, it may cost you $5 but if you buy two, it will cost you $8 instead of $10.

The Problem:

Let’s assume a store provides discounts as follows:

1. No discount if you buy only one.

2. $2 discount for each additional item if you buy more than one.

Given the number of items a customer has purchased and the price for one item, you are to compute the total cost for the customer.#### Input

The first input line contains a positive integer, n, indicating the number of customers to check. The customers are on the following n input lines, one customer per line. Each line provides two integers; the first integer c (1 ≤ c ≤ 100) is the number of items purchased by the customer, and the second integer p (3 ≤ p ≤ 50) is the price for one item.

#### Output

For each customer, print two lines of output. The first line will contain the two input values separated by a single space. The second output line will contain the total cost for the customer. There should be no leading or trailing spaces on any output line.
