Category: 09. Binary Trees

A subgraph T of a connected graph G is called spanning tree of G if T is a tree and T include all vertices of G. Minimum Spanning Tree: Suppose G is a connected weight graph i.e., each edge of G is assigned a non-negative number called the weight of edge, then any spanning tree…

Binary search trees have the property that the node to the left contains a smaller value than the node pointing to it and the node to the right contains a larger value than the node pointing to it. It is not necessary that a node in a ‘Binary Search Tree’ point to the nodes whose…

Traversing means to visit all the nodes of the tree. There are three standard methods to traverse the binary trees. These are as follows: 1. Preorder Traversal: The preorder traversal of a binary tree is a recursive process. The preorder traversal of a tree is 2. Postorder Traversal: The postorder traversal of a binary tree is a…

If the outdegree of every node is less than or equal to 2, in a directed tree than the tree is called a binary tree. A tree consisting of the nodes (empty tree) is also a binary tree. A binary tree is shown in fig: Basic Terminology: Root: A binary tree has a unique node called…

A graph which has no cycle is called an acyclic graph. A tree is an acyclic graph or graph having no cycles. A tree or general trees is defined as a non-empty finite set of elements called vertices or nodes having the property that each node can have minimum degree 1 and maximum degree n.…
