Maximum independent set

CodingAlgorithms & data structuresSenior–Staff~35 min

You are given a bipartite graph with nL left nodes and nR right nodes and edges [a, b]. Return the size of a maximum independent set: the largest set of nodes such that no edge connects two chosen nodes. Constraints: 1 <= nL, nR <= 60.

Implement
max_independent_set(nL: int, nR: int, edges: list[list[int]]) → int
Examples

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.
