: Question 12: Code the given problem using python
The Physics teacher in Alexandra’s class is teaching concepts of a bouncing ball. The
rubber ball that she is using has the property that if the ball is dropped from height H
then, it bounces back to maximum height H/F. So, after first bounce it rises up to
maximum height H/F, after second bounce to maximum height H/F?, after third bounce
to maximum height H/F3, and so on.
The class has N children, and the teacher wants to select two children such that when
the taller child drops the ball from his height, ball reaches a maximum height equal to the
height of the shorter child after some (possibly zero) number of bounces. Note that zero
bounces mean heights of the two children will be same. Given the heights of the children
in the class Height[), can you tell how many ways are there for the teacher to select two
children for the demonstration? Note that when heights are same, the pair is only
counted once (See input and output for further clarification).
