Types of Binary Tree | Binary Tree Introduction

August 1, 2018
Posted by Abhi Andhariya

This is the third article in the tree data structure series. In our previous two articles, we have seen some of the tree data structure terminologies like Nodes, Edges, Root, Parent, Children, Leaves, Siblings, Degree of Tree, Path, Level, Depth, Height and sub tree.  In this article, we will discuss difference between tree and binary tree. We […]

Tree Data Structure Terminologies – Set 2

July 2, 2018
Posted by Abhi Andhariya

In our previous article on Tree Terminologies, we have seen basic tree terminologies like Nodes, Edges, Root, Parent, Children, Leaves and Siblings. In this article, we will understand Degree of Tree, Path, Level, Depth, Height and sub tree.  Degree Total number of children of a node is called Degree of that node. The Degree of […]

In this article, we will discuss one of the important non-linear data structure in computer science, Tree. Many real-life problems can be represented and solved using Tree data structure.  In this article, we will understand basic tree terminologies like Nodes, Edges, Root, Parent, Children, Leaves and Siblings. In next article on tree terminologies, we will see  terms […]

Graph Search – Depth First Search

Posted by Dipen Adroja

We discussed about basic search mechanisms for Graph and Breadth First Search(BFS) in previous article. In this article we will start with basic definition of the Depth First Search(DFS). Depth First Search(DFS): In depth first search, we start from the root node then traverse the graph layerwise until we reach the leaf or dead end. In short, One […]

Graph Search – Breadth First Search

In Our previous article about Graph, we have seen the different ways to represent the graph.  we have a way to represent this unstructured data structure.  Now question arise is how I will traverse through this given graph structure.  There are main two methods which we will use to traverse through graph.  Breadth First Search […]

Stack Implementation Using Array

Posted by Abhi Andhariya

A stack is a container of objects that are inserted and removed according to the last-in first-out (LIFO) principle. A stack is a limited access data structure – elements can be added and removed from the stack only at the top. push operation adds an item to the top of the stack. pop removes the item from […]

Graph

Graph is a non linear data structure, it contains a set of points known as nodes (or vertices) and set of links known as edges which connects the vertices. The pictorial representation is shown in the image in the left pane. Types of Graph: Undirected Graph is a graph that is a set of vertices connected by edges, where the […]

Heap (Min/Max Heap)

Posted by Dipen Adroja

What is heap? Heap is a balanced binary tree data strucure where the root-node key is compared with its children and arranged accordingly. Max Heap: Root element will always be greater than or equal to either of its child element( see the image on left pane). Min Heap: Root element will always be less than or equal […]

Linked List

Posted by Dipen Adroja

A linked list is a dynamic data structure which is consist of nodes and links. The number of nodes in a list is not fixed and can grow and shrink on demand. As Discussed in previous article of ArrayList, this structure will provide us more space effective insertion/deletion for intermediate elements. In this structure it will […]

Array List

March 31, 2017
Posted by Dipen Adroja

We can think, arraylist as an array having collection of items which can grow and shrink dynamically. Before going further one question should arise Why we want to use array list instead of array? Answer is very simple, when we need a data structure which have all the array capabilities and is also efficient at […]
