Given a directed, acyclic graph of N nodes. Find all possible paths from node 0 to node N-1, and return them in any order. The graph is given as follows: the nodes are 0, 1, …, graph.length - 1. graph[i] is a list of all nodes j for which the edge (i, j) exists. Exa...

There are two paths: 0 -> 1 -> 3 and 0 -> 2 -> 3. Note: The number of nodes in the graph will be in the range[2, 15]. You can print different paths in any order, but you should keep the order of nodes inside one path. 这道题给了我们一个无回路有向图,包含N个结点,然后...

Neighboring Nodes: For each node, we iterate over its neighbors to explore possible paths. This operation takes constant time per neighbor. 4.2 Space Complexity: Queue: The space complexity of the queue is proportional to the maximum number of nodes that can be in the queue at any given time...
