Question
You receive integers one at a time from a stream. After each new integer, report the median of all integers seen so far. Return a list of medians (as floats), one per input element. The median of an even count is the average of the two middle values. nums has at least one element.
Implement
running_medians(nums: list[int]) → list[float]Examples

[[1,2,3,4]]out[1,1.5,2,2.5]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.
