Welcome to your interview.
The question is on your right: Approaching Medium LeetCode Problems. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How would you approach a medium-level LeetCode problem in an interview? Walk me through how you identify the pattern, choose a data structure, and reason about time and space complexity before coding.
