WebAug 23, 2024 · Example 12.5.1 . The preorder enumeration for the tree of Figure 12.5.1 is A B D C E G F H I. The first node printed is the root. Then all nodes of the left subtree are printed (in preorder) before any node of the right subtree. ... Postorder and inorder traversals are similar. They simply change the order in which the node and its children … WebWe can construct a unique binary tree from inorder and preorder sequences and the inorder and postorder sequences. But preorder and postorder sequences don’t provide enough information to create a unique binary tree. Several binary trees can be constructed due to ambiguity. For example, consider the following skewed trees:
