Rectangle Perimeter

Given a rectangle with width w and height h, calculate its perimeter using the formula: \(P = 2(w + h)\). Your program should read input from standard input (stdin) and output the result to standard output (stdout). This is a simple arithmetic problem designed to test basic I/O operations and expression evaluation.

inputFormat

The input consists of a single line containing two space-separated integers representing the width w and the height h of the rectangle.

outputFormat

Output a single integer: the perimeter of the rectangle.
