Your question is Algorithm Analysis. 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).
Read this algorithm and explain its purpose and potential edge cases.
Describe what the algorithm computes, how its control flow produces that result, and what assumptions it makes about its inputs. Identify boundary cases, invalid or unexpected inputs, possible correctness problems, and the algorithm’s time and space complexity. Explain how you would validate the analysis with representative examples and tests.
