# 797. All Paths From Source to Target

## Description

Given a directed acyclic graph (**DAG**) of `n`

nodes labeled from `0`

to `n - 1`

, find all possible paths from node `0`

to node `n - 1`

and return them in **any order**.

The graph is given as follows: `graph[i]`

is a list of all nodes you can visit from node `i`

(i.e., there is a directed edge from node `i`

to node `graph[i][j]`

).

**Example 1:**

Input:graph = [[1,2],[3],[3],[]]Output:[[0,1,3],[0,2,3]]Explanation:There are two paths: 0 -> 1 -> 3 and 0 -> 2 -> 3.

**Example 2:**

Input:graph = [[4,3,1],[3,2,4],[3],[4],[]]Output:[[0,4],[0,3,4],[0,1,3,4],[0,1,2,3,4],[0,1,4]]

**Constraints:**

`n == graph.length`

`2 <= n <= 15`

`0 <= graph[i][j] < n`

`graph[i][j] != i`

(i.e., there will be no self-loops).- All the elements of
`graph[i]`

are**unique**. - The input graph is
**guaranteed**to be a**DAG**.
