Even Product or Sum

This problem requires you to read two integers, \(x\) and \(y\), from standard input and compute the product \(P = x \times y\). If \(P\) is even (i.e. \(P \mod 2 = 0\)), then output \(P\). Otherwise, output the sum \(x + y\). This simple conditional task is designed to test your basic arithmetic and input/output handling skills.

inputFormat

The input consists of two space-separated integers, x and y, provided on a single line via standard input.

outputFormat

Print a single integer to standard output: the product x*y if it is even, or the sum x+y if the product is odd.## sample
