Minimum edge cut

CodingAlgorithms & data structuresSenior–Staff~40 min

Given an undirected graph with n nodes (0..n-1) and edges [u, v] (each edge has unit strength), find the minimum number of edges whose removal disconnects a given source node from a given sink node. If they are already disconnected, return 0. Parallel edges count separately. Constraints: 1 <= n <= 200.

Implement
min_edge_cut(n: int, edges: list[list[int]], source: int, sink: 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.
