Your final grade is determined by a midterm component (each midterm is worth 20% of the grade) and a final component. In order to avoid any discrepancies with students who’s grades are on the fence, your teacher follows this strict grading scale: [0%,60%) = F, [60%, 70%) = D, [70%, 80%) = C, [80%, 90%) = B and [90%, 100%] = A. He does not round until the very end. Construct a function that determines a student’s final grade percentage according to this grading scheme and prints the result.
