PROBLEM 1 Total: 30 Points Write a MATLAB script that asks the user to enter a whole number (i.e., any whole number, positive, negative or zero). After the number is entered, the program must utilize an IF-ELSE statement and determine the parity of the number. The parity of a number is simply whether it is an even number oi an odd number. If the number is even, MATLAB must then generate and display the message: The entered number is an even number. Otherwise, MATLAB must generate and display the message: The entered number is an odd number (Hint: What basic property of numbers makes them odd or even? What existing MATLAB function that we discussed in class can we take advantage of to determine the parity of numbers?) PROBLEM 2 Total: 30 Points Write a MATLAB script to determine and display a student's letter grade in a course. A course grade is typically reported as a real number with values from 0 to 100. Your algorithm should ask the user to provide a grade in numerical form and display the letter grade corresponding to the numerical grade if the entered value is between 0 and 100 inclusive. If the value is outside of this range, ask the user to re-run the program and enter a value within the range of 0-100. Typical ranges for grades are given below A: 90 S grade B: 80 grade . Your letter grade is At the location given bynumerical grade specified by user>, the program must display the numerical grade that the user just entered, and at the location given by , the program must display the letter grade that it calculated based on the user's input. Therefore, if the user entered a score of 74, the message must show: You earned a score of 74. Your letter grade is B. Similarly, if the user entered a grade of 56, the message must show: You earned a grade of 56. Your letter grade is F
