findAverage


The method findAverage() takes an arraylist of doubles and returns the average after the high and low scores are removed.
Preconditions:
The list will be at least 3 numbers long.
There will never be a tie for highest or lowest.


findAverage([100.0, 30.5, 50.5, 99.0, 77.0, 45.5]) → 68.0
findAverage([67.5, 36.5, 69.5, 88.0, 99.5, 76.5, 82.5]) → 76.8
findAverage([55.0, 66.0, 77.0, 88.0, 99.0, 44.0, 55.0]) → 68.2

...Save, Compile, Run (ctrl-enter)

public double findAverage(ArrayList<Double> lst){ }
