A school needs a program to manage term scores for its students. The program must: 1. Prompt for the number of students (n). 2. For each student, read the student's name and three test scores (each out of 100). 3. Compute the total and average score for each student. 4. Assign a grade according to the average: A ≥ 70, B 60‑69, C 50‑59, D 45‑49, F < 45. 5. After all data are entered, display a summary table showing Name, Total, Average (to one decimal place) and Grade, sorted in descending order of average. Write the solution in Python and answer the questions that follow.
