Do NOT process this value. You can assume that the user will enter at least three grades and not more than 100 grades, all of which will be integers in between 0 and 100, inclusive. For the set of grades, your program should compute the minimum value, print this out to two decimal places and remove it from the data. Then your program should compute the maximum value, print it out to two decimal places and remove it from the data.
