sign_of(n) that returns "Positive" if n is greater than zero, "Negative" if less than zero, and "Zero" if it equals zero. A classic three-way if/elif/else branch.sign_of(-5)
"Negative"
-5 is less than 0.
sign_of(0)
"Zero"
0 is neither positive nor negative.
Check for zero first or last — order matters for readability, not correctness here.
Use if / elif / else, not three separate ifs.
