Question

Given two sorted integer arrays a and b, return the median of the combined sorted array as a float. Either array may be empty (but not both). The combined length is at least 1. Return a float (e.g. 2.0 or 2.5).

Implement
median_two_sorted(a: list[int], b: list[int]) → float
Examples
in[[1,3],[2]]out2
What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.

Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.

Run or narrate your approach, then ask the coach.
