Input

One line of a decimal positive value bounded between 20.0 and 20,000.0.

Output

The output of this problem is made by three lines: * First line the identified note corresponding to the input frequency * Second line the closest note with the proper octave frequency * Third line the correction to make the input frequency sound perfectly pitched. If the input frequency is already perfectly pitched, then the output may be slightly different. Check the examples!

In case the frequency given lays just in the middle of two notes, it is preferable to increase the frequency instead of decreasing.

All values must be rounded to one decimal.
