The Model

You are making a model airplane, which will be powered by rubber bands. Luckily, to speed up the process of winding the rubber bands, you have a crank winder, which has a certain ratio (e.g. 15:1), representing how many winds of the rubber band one turn of the winder will result in. Given this value, and how many winds you ultimately want the airplane's rubber band to have, figure out how many times you need to turn the winder.

Input

The first line of input contains a single positive integer $$$n$$$, representing the number of winds you want the plane to have. The second line of input contains a single positive integer $$$m$$$, representing how many winds of the rubber band one turn of the winder corresponds to.

Output

Output a single positive integer $$$w$$$: how many times you need to spin the winder. This value is guaranteed to be an integer.

Note

For the first example, $$$150.0$$$ would also be judged as a correct answer.
