classify_parity(n) that returns the string "Even" if the integer n is even, and "Odd" otherwise. This is the smallest possible if/else warm-up — get the branch condition exactly right.classify_parity(4)
"Even"
4 is divisible by 2.
classify_parity(7)
"Odd"
7 is not divisible by 2.
Use the modulo operator `%` to test divisibility by 2.
Zero counts as even.
