voidpostOrderTraversal(BinaryTree *p) {if(!p)return; postOrderTraversal(p->left); postOrderTraversal(p->right); cout<< p->data; } This is the most difficult of all types of iterative tree traversals. You should
When we wanted to display a binary tree, we need to follow some order in which all the nodes of that binary tree must be displayed. In any binary tree, displaying order of nodes depends on the traversal method. Displaying (or) visiting order of nodes in a binary tree is called as Bin...

If I understand the exercise correctly, you would have to come up with formulas for how to calculate the label of the left and right child during each method of traversal, given the label of the current node and the depth. For example, during pre-order traversal, the ...

A unique binary tree can be determined by a given pair of postorder and inorder traversal sequences, or preorder and inorder traversal sequences. However, if only the postorder and preorder traversal sequences are given, the corresponding tree may no longer be unique. Now given a pair of ...
