The delete (temp); before the print (root); might cause a problem. Also the logic for adding the nodes doesn't look right. With only one delete this will leak memory, but this will not be stopping you from printing the data. Please put in the code playground. ...

Let’s try printing root 1,bnt1, to see what we get. Example code: print(bnt1.printTree()) Output: The output shows that the tree contains two nodes (the left node and the right node). The data in the left node is2, and in the right node is3. ...

A node's children are those nodes that appear immediately beneath the node itself. A node's parent is the node immediately above it. A tree's root is the single node that contains no parent.Figure 1 shows an example of the chain of command in a fictional company....
Given a non-empty binary tree, find the maximum path sum. For this problem, a path is defined as any sequence of nodes from some starting node to any node in the tree along the parent-child ... Threaded Binary Tree “一个二叉树通过如下的方法“穿起来”:所有原本为空的右(孩子)指针改为...
Given a binary tree, return the postorder traversal of its nodes' values.For example:Given binary tree {1,#,2,3},1 \ 2 / 3 return [3,2,1].Note: Recursive solution is trivial, could you do it iteratively?We know the elements can be printed post-order easily using recursion, as ...
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. Evaluatingpost-fix notation. ...
