Post-order traversal is useful in some types of tree operations: Tree deletion. In order to free up allocated memory of all nodes in a tree, the nodes must be deleted in the order where the current node can only be deleted when both of its left and right subtrees are deleted. Evaluatin...
Suppose that all the keys in a binary tree are distinct positive integers. 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 giv...
For each test case, first printf in a lineYesif the tree is unique, orNoif not. Then print in the next line the inorder traversal sequence of the corresponding binary tree. If the solution is not unique, any answer would do. It is guaranteed that at least one solution exists. All th...
My DAG evaluation is similar to the examples except that: 1) The graph topology is not known a priori and can change with each evaluation, 2) post-order traversal is required since the results of evaluating a node depends on the results of its predecessor nodes, and 3) cont...

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 ...
