You're given two strings of equal length. Your task: compare them case-insensitively and output -1 if the first is smaller, 1 if the second is smaller, or 0 if they're equal. The challenge tests your ability to process strings character by character.
You'll need to convert letters to the same case before comparing, then determine which string is lexicographically smaller. This is a string manipulation problem where case normalization is the trick.
Read the statement and think about how you'd handle mixed case.
