Find path between two nodes in a tree
WebSep 4, 2024 · If the two nodes are in different subtrees of root nodes − When the two nodes are in different subtrees like one in left and other in right. In this case, it is clear that the root node will lie in between the path from node1 to node2. So, print path1 in reverse order and then path2. WebNov 11, 2024 · For one, both nodes may be in the same component, in which case there’s a single simple path. The reason is that both nodes are inside the same tree. On the other hand, if each node is in a different …
