A binary tree is a tree where each node may only have up to two children. These children are stored on theleftandrightproperties of each node. When traversing a binary tree, we have three common traversal algorithms: in order, pre-order, and post-order. In this lesson, we write each o...

Nonnumerical Algorithms and Problems-traversalsStarting from a stack-based binary tree traversal algorithm for preorder and/or inorder, we derive an algorithm recently discovered by J. M. Morris which requires neither stack nor tag fields. This algorithm may also be derived from the familiar ...
After a long time I took a look in algorithms and data structure and what I wrote first inBinary Treeand its different traversal in C++. I have never written them in python so I tried to write one.And yes writing them down in python is lot more easier. So lets me first introduce you...
On breadth-first traversal, you visit the tree on its breadth i.e. all nodes of one level are visited before you start with another level top to bottom. The PreOrder, InOrder, and PostOrder traversals are all examples of depth-first traversal algorithms. While traversing a tree, you need...

Traversals A traversal is a process that visits all the nodes in the tree. Since a tree is a nonlinear data structure, there is no unique traversal. We will consider several traversal algorithms with we group in the following two kinds ...
BST can be used to implement various efficient searching algorithms. BST is also used in applications that require a sorted list as input like the online stores. BSTs are also used to evaluate the expression using expression trees. Conclusion ...
