Description

This problem's author is too lazy-to-write the problem description, so he only give you a equation like x (ey) = = (ey) x, And the value of Y, your task is calculate the value of X.
Note:here e is the Natural logarithm.

Input

Each line would contain one number Y (y >= 1). Process to end of file.

Output

For each case, output X on one line, accurate to five decimal places, if there is many answers, output them in increasing Order, if there is no answer, just output "Happy to women ' s day!".

Sample Input

1

Sample Output

2.71828
