Welcome to your interview.
The question is on your right: Data Structure for Sensor Coordinates. 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.
Which data structure would you choose to store rapidly updating sensor coordinates for Kernel, and why?
