The problem is so easy, that the authors were lazy to write a statement for it!

Input

The input stream contains a set of integer numbers

 

A_i

 (0 ≤

 

A_i

 ≤ 10

¹⁸). The numbers are separated by any number of spaces and line breaks. A size of the input stream does not exceed 256 KB.

Output

For each number

 

A_i

 from the last one till the first one you should output its square root. Each square root should be printed in a separate line with at least four digits after decimal point.
