Solution: All Paths From Source to Target

Explore how to solve the problem of finding every path from the source node to the target node in a directed acyclic graph by using DFS combined with backtracking. This lesson teaches you how to systematically explore all routes without redundancy and handle path tracking to return complete solutions, preparing you for combinatorial coding interview questions.

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 ...
