Write a method called public double findAvgDroppingLowest(int x, int y, int z) that will find the average, dropping the lowest value and return that value. So if findAvgDroppingLowest (5,2,8) gets called, it returns 6.5 (it drops 2, and finds avg of 5 and 8). If there are 2 or 3 lowest it drop just one of them.
