Calculate Card Perimeters

You are given several queries, each representing the dimensions of a rectangular card. For each query, you need to compute the perimeter of the card using the formula:

$$ P = 2 \times (w + h) $$

where w is the width and h is the height of the card.

The input starts with an integer T representing the number of queries. Then, T lines follow, each line containing two space-separated integers indicating the width and height of a card. For each query, output the computed perimeter on a new line.

This is a simple problem intended to test your ability to perform basic arithmetic operations and handle multiple test cases.

inputFormat

The first line of input contains a single integer T (1 ≤ T ≤ 10⁴) denoting the number of queries. Each of the next T lines contains two space-separated integers w and h (1 ≤ w, h ≤ 10⁴) representing the width and height of a card.

outputFormat

For each query, output the perimeter of the card on a separate line. The perimeter is calculated using the formula: $$ P = 2 \times (w + h) $$## sample
