Case Flipper
This kind of text transformation is common when you need to scan a string and change each letter. Write a function to_alternating_case that takes a string string and inverts the case of every letter: lowercase becomes uppercase, and uppercase becomes lowercase. Spaces, digits, and other characters should stay unchanged.
