Please create an array of student names and another array of student grades.
Create a function that can put a name and a grade to the arrays.
Keep Read student name and grade until student name is “???”. And save the reading by using a function
Create another function to show all the grade in that object.
Create the third function that can display the maximum grade and the student’s name.
Create a sorting function that can sort the arrays based on the student’s grade.
Display all the grades and names sorted by the grade.
