PROGRAMMING:Falling ball
The ball falls freely from a given height, rebounds to half of the original height after touching the ground, falls again, rebounds again,... And so on. How much distance does the ball pass in the air when it lands for the $$n $? What is the height of the $$n $$rebound?
###Input format:
The input gives two non negative integers in one line, which are the initial height of the ball and $$n $$, both of which are in the range of long integers.
###Output format:
Output the distance the ball passed in the air when it landed for the $$n $$th time, and the height of the ball rebounded for the $$n $$th time in one line, separated by a space, with one decimal place reserved. The calculation results should not exceed the double precision range.
###Input example:
```in
33 5
```
###Output example:
```out
94.9 1.0
```
