🧠 Today’s Homework — Very Important!

1. You may use any editor or IDE to write your program.
   However, your code must compile and run correctly in the grading environment (Linux / GCC).

2. If your program does not compile, you will receive 0 points,
   even if the logic is correct.

3. Please test your program thoroughly using the provided test cases.
