Write a class Grade that reads a score (an int) and prints the letter grade:
| Score | Grade |
|---|---|
| 90–100 | A |
| 80–89 | B |
| 70–79 | C |
| 60–69 | D |
| 0–59 | F |
Print it as Grade: B. If the score is below 0 or above 100, print Invalid score instead.
Problem
Write it here or in your IDE, then paste it. Compile and test it yourself before comparing. Your code stays in your browser — it is never sent to or stored on the server.
