Problem Statement:
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 Format:
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 Format:
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.

Sample Input:
2 1 5 3 10

Sample Output:
1 5 5 3 10 26
