* Title: A ball falls freely from a height of 100 meters. After each landing, it bounces back to half of its original height. If it falls again, find it at
How many meters did you pass when you landed for the nth time? How high will it bounce after landing?
* Program analysis: The height of the n-th bounce is half of the previous bounce. When counting how many meters passes, it does not count the height of the bounce * /
