Welcome to your interview.
The question is on your right: Searching in a Binary Search Tree. 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.
Walk through how you search for a value in a binary search tree. Explain the decision made at each node and give the time complexity in balanced and worst-case cases.
