Your question is Walk me through your approach to an algorithmic problem. 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).
Can you walk me through your approach to this algorithmic problem? Please explain how you clarify requirements, identify an appropriate strategy, evaluate time and space complexity, and validate your solution. I am interested not only in the final answer, but also in how you communicate trade-offs, respond to ambiguity, and take ownership of correcting your approach when new information appears.
