Question

Given a list of integers nums, return the second largest distinct value. If there is no second distinct value (the list is empty or every element is equal), return None. Example: [3, 1, 3, 2] has distinct values {1,2,3}, so the answer is 2.

Implement

second_largest(nums: list[int]) → int | None

Examples

in[[3,1,3,2]]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.

Learn the concepts

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.
