feat: Calculate average of three subject marks and assign grade based on range

🧠 Logic:
- Reads marks for three subjects (m1, m2, m3).
- Computes the average of the marks.
- Determines grade based on average:
  - ≥70 → Grade A
  - 60–69 → Grade B
  - 50–59 → Grade C
  - 40–49 → Grade D
  - <40  → Grade E
