Solution: All Paths From Source to Target
Explore how to use depth-first search combined with backtracking to find all possible paths from the source node to the target node in a directed acyclic graph. Understand the recursive approach, path tracking, and why the lack of cycles ensures efficient traversal. This lesson helps you implement and reason about graph pathfinding in coding interviews.

Statement
You are given a directed acyclic graph (DAG) with 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
