Countdown
Print a countdown from 9 to 0.
Write a program that prints the digits 9 through 0, each on the same line.
Requirements:
• Output must be exactly: 9876543210
• Use a loop (don't just print each character individually)
• Halt after printing
Hint: ASCII '0' is 48 (decimal). To convert a digit n to its ASCII representation, add 48.
