Create a method called getTotalScore that has 1 array parameter, and returns the total in the array

Create a method called getLowestScore that has 1 array parameter, and returns the lowest element in the array

Create a method called getHighestScore that has 1 array parameter, and returns the highest element in the array

Create a method called getAverage that has 2 parameters (the totalScore and size of the array), and returns the average score

Create a method called printGrade, that takes 1 parameter (your average score), and prints out your grade, based on the grade scale that is on our course Syllabus. [
