WebApr 27, 2024 · A threaded tree node typically has a flag that tells you whether the right and left pointers in the node are references to children, or threads to the inorder/preorder successor. That's the only way you can tell if the node is a leaf. The nice thing about a threaded tree is that inorder or reverse inorder traversals can be done quickly without …
