What Is Spanning Tree in Data Structure With Example?
In the field of computer science and data structures, a spanning tree is a special type of connected acyclic graph. It is derived from a given graph and contains all the vertices of the graph. A spanning tree has the minimum possible number of edges that are required to connect all the vertices.
A graph is a collection of nodes (also known as vertices) connected by edges. Each edge represents a relationship or connection between two nodes. A graph can be represented visually as a set of points (vertices) connected by lines (edges).
A spanning tree can be useful in various applications, such as network design, as it helps to create an efficient and minimal structure for connectivity.
Properties of Spanning Trees:
- A spanning tree must include all the vertices from the original graph.
- A spanning tree cannot contain any cycles, which means there should be no repeated edges or loops.
- A spanning tree must have exactly n-1 edges, where n is the number of vertices in the original graph.
Example:
Let’s consider an example to understand how to find a spanning tree for a given graph.
We have a graph with 5 vertices: A, B, C, D, and E. The edges are represented by lines connecting these vertices.

To find a spanning tree for this graph, we need to ensure that it satisfies all the properties mentioned earlier. One possible spanning tree for this example could be:

In this spanning tree, we have exactly 4 edges (n-1) connecting all the vertices without any cycles. It covers all the nodes of the original graph and provides a minimal structure for connectivity.
Conclusion:
A spanning tree is a crucial concept in data structures and graph theory. It helps in creating an efficient and minimal structure to connect all the vertices of a graph. By understanding the properties and examples of spanning trees, you can apply this knowledge in various applications like network design and optimization.

What Is the Spanning Tree in Data Structure? The spanning tree is a fundamental concept in graph theory and data structures. It is a subgraph of a connected, undirected graph that includes all the vertices of the original graph.
In data structures, tree traversing refers to the process of visiting each node in a tree data structure exactly once. Trees are hierarchical structures consisting of nodes connected by edges, with a single node at the top known as the root. Traversing a tree allows us to access its elements in a specific order, enabling various operations like searching, inserting, and deleting nodes.
A complete tree in data structure refers to a type of binary tree where all levels, except possibly the last one, are completely filled with nodes. In other words, a complete tree is a binary tree in which each level is filled from left to right. Properties of a Complete Tree:
A complete tree has the following properties:
Level Filling: All levels of the tree are filled except possibly the last level.
A complete tree, also known as a full binary tree, is a special type of binary tree in data structure. In a complete tree, all levels are completely filled except possibly for the last level, which is filled from left to right. Properties of a Complete Tree
A complete tree has the following properties:
Fullness: Every level except the last level is completely filled with nodes.
A complete tree is a type of binary tree where all levels, except possibly the last one, are completely filled with nodes. In other words, a complete tree is a binary tree in which each level is filled from left to right. Properties of Complete Trees:
Full Binary Tree: A complete tree is also referred to as a full binary tree because all nodes have either 0 or 2 children.
A high balanced tree, also known as an AVL tree, is a self-balancing binary search tree in data structure. It was named after its inventors, Adelson-Velsky and Landis. The main objective of a high balanced tree is to maintain a balance between the left and right subtrees.
A multi-way tree, also known as a general tree or an ordered tree, is a data structure that allows multiple children for each node. Unlike binary trees, which have at most two children per node, multi-way trees can have any number of children. In this article, we will dive deeper into the concept of multi-way trees and explore their various properties and applications.
