Question
You manage n people labeled 1..n and must split them into two teams. You're given a list of dislike pairs [a, b] meaning a and b refuse to be on the same team. Return True if such a split is possible (every disliking pair ends up on different teams), otherwise False. The graph may be disconnected and a person may have no dislikes. There are at most 2000 people.
possible_split(n: int, dislikes: list[list[int]]) → bool[4,[[1,2],[1,3],[2,4]]]outtrueState 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.
