Question
Given a directed graph with n nodes (0..n-1) and edges [u, v], find the maximum number of internally vertex-disjoint paths from a given source to a given sink: paths that share no intermediate vertex (they may share only the source and sink). Return that count. Constraints: 1 <= n <= 100.
Implement
max_vertex_disjoint_paths(n: int, edges: list[list[int]], src: int, dst: int) → intExamples

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.
