Felt almost too easy at first so I kept waiting for a twist that never came.
Start by clarifying the input format and constraints, then propose a single-pass algorithm that tracks min and max for both x and y. After coding, walk through a small example to verify correctness and discuss time/space complexity.
Pro tip: Mention that you can compute everything in one pass, which is optimal, and handle edge cases like empty list or single point. Also, note that the ranges are simply max - min for each coordinate.
Ask about input size, data types, whether the list can be empty, and if there are any memory or time constraints.
Explain that you will iterate through the list once, maintaining current min and max for x and y, then compute ranges as differences.
Write clean code with appropriate variable initialization (e.g., using first element or infinity) and handle edge cases.
Walk through a sample input, including edge cases like empty list or single point, to demonstrate correctness.
State that time complexity is O(n) and space is O(1), and discuss potential optimizations or trade-offs.
