Solution: All Paths From Source to Target

Explore the method to find every path from the source node to the target in a directed acyclic graph by applying depth-first search with backtracking. Understand how to recursively traverse the graph, manage path tracking, and ensure all routes are covered efficiently without cycles. This lesson helps you implement and reason about the search process to solve similar graph traversal challenges.

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 ...
