Solution: All Paths From Source to Target

Explore how to find all paths from the source node to the target node in a directed acyclic graph using depth-first search and backtracking. This lesson helps you understand recursion, path tracking, and pruning techniques to efficiently handle graph traversal without cycles, enabling you to solve similar graph path problems confidently.

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 ...
