Your question is Explain Big O Notation and Usage. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about Big O notation, and what it is used for in software development.
Explain how Big O describes an algorithm's time and space growth as input size increases. Include one concrete example and distinguish complexity analysis from measuring an implementation's exact runtime.
