\n", "translatedTitle": "所有可能的路径", "translatedContent": "

给定一个有 n 个节点的有向无环图，用二维数组 graph 表示，请找到所有从 0 到 n-1 的路径并输出（不要求按顺序）。

\n\n

graph 的第 i 个数组中的单元都表示有向图中 i 号节点所能到达的下一些结点（译者注：有向图是有方向的，即规定了 a→b 你就不能从 b→a ），若为空，就是没有下一个节点了。

示例 1：

\n\n

\"\"

\n\n
\n输入：graph = [[1,2],[3],[3],[]]\n输出：[[0,1,3],[0,2,3]]\n解释：有两条路径 0 -> 1 -> 3 和 0 -> 2 -> 3\n
\n\n

示例 2：

\n\n

\"\"

\n\n
\n输入：graph = [[4,3,1],[3,2,4],[3],[4],[]]\n输出：[[0,4],[0,3,4],[0,1,3,4],[0,1,2,3,4],[0,1,4]]\n
\n\n

示例 3：

\n\n
\n输入：graph = [[1],[]]\n输出：[[0,1]]\n
\n\n

示例 4：

\n\n
\n输入：graph = [[1,2,3],[2],[3],[]]\n输出：[[0,1,2,3],[0,2,3],[0,3]]\n
