 /**

* Shape

Define a class named Rectangle:

It should have length and width as the properties.

It should have a method, named calculatePerimeter, which should return the perimeter

of the rectangle.

It is given that, length and width will always be valid.

You don't need to worry about input/output and object of the class. The given template

will take care of it.

The input will contain the length and width.

Input

One line containing two space seperated integers, denoting length and width respectively.

Output

Print perimeter of the given rectangle.

Example

Input1:

10 20

Output1:

60
