Schreiben Sie bei einem gegebenen Binärbaum eine iterative und rekursive Lösung, um den Baum mit Postorder-Traversal in C++, Java und Python zu durchlaufen. Im Gegensatz zu verknüpften Listen, eindimensionalen Arrays und anderen linearen Datenstrukturen, die in linearer Reihenfolge durch...

Suppose that all the keys in a binary tree are distinct positive integers. Given the preorder and inorder traversal sequences, you are supposed to output the first number of the postorder traversal sequence of the corresponding binary tree. Input Specification: Each input file contains one test ...

The program creates a binary tree for breadth-first traversal.But i'm trying to use Pre-Order, In-Order, Post-Order Traversal and actually i can't do that. The output of the program is not what i expected. I think i should change the preorder, inorder or postorder functions but i ...
Here is source code of the C Program to Build Binary Tree if Inorder or Postorder Traversal as Input. The C program is successfully compiled and run on a Linux system. The program output is also shown below. /* * C Program to Build Binary Tree if Inorder or Postorder Traversal as Inpu...
Since we are given the preorder traversal of the tree, to construct any tree we need at least two traversal{inorder,preorder},{inorder,postorder},{inorder,levelorder}that is inorder is needed, but here only one traversal is given but one more important thing is the property of this tre...
