) Design an algorithm and write a program using for loop that calculates the total grade for N classroom exercises as a percentage. The user should input the value for N followed by each of the N scores and totals. Calculate the overall percentage (sum of the total points eamed divided by the total points possible) and output it as a percentage. Sample input and output is shown below. How many exercises to input? 3 Score received for exercise 1: 10 Total points possible for exercise 1: 10 Score received for exercise 2: 7 Total points possible for exercise 2: 12 Score received for exercise 3: 5 Total points possible for exercise 3: 8 Your total is 22 out of 30, or 73.33%. k) Rewrite the program using while loop
