Dear Instructor, I promise I didn’t use ChatGPT for this... or did I? 😏
I worked so hard, even my laptop cried. Please reward me with a 100%! 🥺
If I don’t get 100%, my pet rock will be very disappointed. 🪨
P.S. I’ll name my firstborn after you if you give me full marks. Deal? 🤝

🔄 Step 9: Clear Screen & Exit (Do it Yourself 😉)

clear
exit
