alpha_descent

Your mission

Write a program that prints the alphabet from Z down to A, alternating case in groups of two letters.

./alpha_descent | cat -e

Expected result

Your checklist

For your own tracking. Tests grade your code.

Output all 26 letters in descending order, from Z to A.
Case switches every two letters: the first two are uppercase, the next two lowercase, then uppercase again, and so on.
No arguments are accepted; if any are passed, ignore them and print the same output.
End the output with a newline.
