Solution: All Paths From Source to Target

Explore how to identify every possible path from a source node to a target node in a directed acyclic graph. Learn to apply depth-first search combined with backtracking to systematically traverse the graph and collect valid paths. This lesson enables you to handle combinatorial problems by understanding recursion and backtracking techniques effectively.

Statement

You are given a directed acyclic graph (DAG) with nn nodes, labeled from 00 to n1n - 1. The graph is represented as an adjacency list, where graph[i] is a list of all nodes to which node i has a directed edge to.

Your task is to find all possible paths from node 0 ...
