<p>给你一个有 <code>n</code> 个节点的 <strong>有向无环图（DAG）</strong>，请你找出所有从节点 <code>0</code> 到节点 <code>n-1</code> 的路径并输出（<strong>不要求按特定顺序</strong>）</p>
|
||
|
||
<p><meta charset="UTF-8" /> <code>graph[i]</code> 是一个从节点 <code>i</code> 可以访问的所有节点的列表（即从节点 <code>i</code> 到节点 <code>graph[i][j]</code>存在一条有向边）。</p>
|
||
|
||
<p> </p>
|
||
|
||
<p><strong>示例 1：</strong></p>
|
||
|
||
<p><img alt="" src="https://assets.leetcode.com/uploads/2020/09/28/all_1.jpg" /></p>
|
||
|
||
<pre>
|
||
<strong>输入：</strong>graph = [[1,2],[3],[3],[]]
|
||
<strong>输出：</strong>[[0,1,3],[0,2,3]]
|
||
<strong>解释：</strong>有两条路径 0 -> 1 -> 3 和 0 -> 2 -> 3
|
||
</pre>
|
||
|
||
<p><strong>示例 2：</strong></p>
|
||
|
||
<p><img alt="" src="https://assets.leetcode.com/uploads/2020/09/28/all_2.jpg" /></p>
|
||
|
||
<pre>
|
||
<strong>输入：</strong>graph = [[4,3,1],[3,2,4],[3],[4],[]]
|
||
<strong>输出：</strong>[[0,4],[0,3,4],[0,1,3,4],[0,1,2,3,4],[0,1,4]]
|
||
</pre>
|
||
|
||
<p> </p>
|
||
|
||
<p><strong>提示：</strong></p>
|
||
|
||
<ul>
|
||
<li><code>n == graph.length</code></li>
|
||
<li><code>2 <= n <= 15</code></li>
|
||
<li><code>0 <= graph[i][j] < n</code></li>
|
||
<li><code>graph[i][j] != i</code>（即不存在自环）</li>
|
||
<li><code>graph[i]</code> 中的所有元素 <strong>互不相同</strong></li>
|
||
<li>保证输入为 <strong>有向无环图（DAG）</strong></li>
|
||
</ul>
|
||
|
||
<p> </p>
