What is Alternating Case?
Alternating case (frequently called Mocking Spongebob case or sArCaSm cAsE) is an internet typography format where letter casing alternates between lowercase and uppercase across character index positions. Popularized across Twitter, Reddit, and meme culture, alternating case conveys a sarcastic, playful, or mocking tone.

How the Algorithm Works
Our algorithm processes character indices sequentially: index 0 begins in lowercase, index 1 switches to uppercase, index 2 returns to lowercase, and so on throughout the entire string, maintaining punctuation and whitespace integrity.
