Problem 1 (List Client)

Suppose that you have a singly linked list that is created by the following statement ListInterface quizScores = new LList(); A professor wants to add to this list quiz scores received by a student throughout a course and find the average of these quiz scores, ignoring the lowest score. Write a Java program at the client level that will:

a. Find and remove the lowest score in the list

b. Compute the average of the scores remaining in the list

c. Print the result.
