A magic expression tests if an integer $M$ satisfies all the following conditions.
- $M$ is greater than 0.
- $M$ is an even number.
- $M$ is greater than 10000, or $M$ is smaller than 1000.
Now given an integer $M$, please assign the magic expression to another integer $N$ and print the value of $N$.
The input contains one integer $M$.
Print the value of $N$, which is the result of the magic expression of $M$.
