Solution: All Paths From Source to Target

Explore the technique of finding all paths from the source node to the target node in a directed acyclic graph using backtracking and depth-first search. Understand how to recursively traverse the graph, track paths, and backtrack to explore different routes. This lesson helps you implement an efficient algorithm for enumerating all valid paths in a DAG.

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 ...
