Using the while loop or the do-while loop write a program that does the following: Calculate the average of a series of homework grades (0 - 100) entered one at a time. In this case the lowest score will be dropped and the average computed with the remaining grades. For example suppose you enter the following grades: 78, 85, 81, 90, 88, 93 and 97. The average will be computed from the 6 grades 85, 81, 90, 88, 93 and 97. The low score of 78 will be dropped. Output each grade, the dropped grade and the final average
