WebNotably, given an infinite tree, the corecursive breadth-first traversal will traverse all nodes, just as for a finite tree, while the recursive depth-first traversal will go down one branch and not traverse all nodes, and indeed if traversing post-order, as in this example (or in-order), it will visit no nodes at all, because it never reaches a leaf. This shows the usefulness of … WebWe can construct a unique binary tree from inorder and preorder sequences and the inorder and postorder sequences.
