Introduction Dijkstra’s Algorithm is used to find the shortest possible distance between two objects. To implement this algorithm we mostly use Priority Queue. In this tutorial, we will find the answer to whether can we use a simple queue to implement Dijkstra’s algorithm instead of a Priority Queue. What is a Priority Queue and A Queue? A queue is a linear array of data. It represents the Queue of real life. A simple Queue uses FIFO (First In First Out) approach for its deQueue and enQueue operations. A priority Queue is a type of Queue that deQueue its elements with ... Read More

Introduction One of the most essential mathematical notations in computer science for determining an algorithm's effectiveness is the Big O notation. The length of time, memory, other resources, as well as a change in input size required to run an algorithm can all be used to evaluate how effective it is. Data structure's Big O Notation provides information about an algorithm's performance under various conditions. In other words, it provides the worst-case complexity or upper-bound runtime of an algorithm. Big O Notation in Data Structure A change in input size can affect how well an algorithm performs. Asymptotic notations, such ... Read More

What is the difference between Business Intelligence and Predictive Analytics?

Updated on 19-Nov-2021 07:10:22
Let us begin by learning about business intelligence.Business IntelligenceBusiness intelligence is an application-driven phase allowing organizations to analyze raw information from various sources, extracting vision that lead to higher effective business results. It is a set of tools and methods that analyze and transform raw information into actionable and coherent data for use in business analysis to support decision-making.Each business has strong transaction-oriented systems that save all information gathered from daily operations into repositories.It can stay competitive, businesses should rediscover and uses the data they influence, and this is where BI appears into play. Business intelligence can change vision from ... Read More

The task of arranging elements of an array in a particular order is referred to as sorting. The sorting of an array or a list is mainly done to make the searching easier. There are two types of sorting algorithms namely, Bubble Sort and Selection Sort. Bubble sort performs sorting of data by exchanging the elements, while the selection sort performs sorting of data by selecting the elements. Read this article to learn more about bubble sort and selection sort and how these two sorting techniques are different from each other. What is Bubble Sort? Bubble sort is a simple ... Read More

The task of arranging the elements of an array in a particular order is referred to as sorting. The sorting of an array or a list is mainly done to make the searching easier. There are several types of sorting algorithms, but in this article, we will concentrate on quick sort and merge sort. Both quick sort and merge sort algorithms are based on the divide-and-conquer sorting algorithms, hence they work almost in a similar way. Read this article to learn more about quick sort and merge sort and how these sorting techniques are different from each other. What is ... Read More

Explain the Difference Between Linear and Non-linear Data Structure

Updated on 23-Mar-2021 07:11:07
In this post, we will understand the difference between linear data structure and non-linear data structure.Linear Data StructureThe elements of such a structure are arranged sequentially.Every element can be accessed by traversing through the linear structure.All the elements of a linear structure are at a single level, i.e there is no hierarchy.They are easy to implement and use.They utilize more memory, hence they are not very memory-friendly.The time complexity of linear data structure usually increases when the size of the structure increases.Examples include- list, array, stackThe below shows an example of a list in Python.my_list = [45, 42, 12, 34, ...

Difference Between Top-down and Bottom-up Parsing

Updated on 02-Mar-2021 05:20:41
In this post, we will understand the differences between top down and bottom-up parsing −Top-down parsing and bottom-up parsing are different techniques to parse a tree to reach the beginning of the tree. This can be done in two different methods, which have been discussed below.Top-down ParsingIt is a parsing technique that looks at the highest level of the parse tree initially, and then works its way down to the parse tree.It does this using the rules of grammar.It uses left most derivation.This parsing method tries to determine the left most derivations for an input string.Here, the parsing is done ...

Updated on 07-Dec-2022 06:00:56
Both Procedural and Non-procedural Languages are widely used in the development of applications and other computer software. Both these types of languages have different approaches on the basis of which we can differentiate them. In this article, we will discuss the important differences between procedural and non-procedural programming languages. Let's start with some basics of procedural and nonprocedural language. What is a Procedural Language? Procedural languages are command-driven or statement-oriented programming languages. A program written using a procedural programming language includes a sequence of statements, and the implementation of each statement generates the interpreter to modify the value of one ...

Difference Between Aggregation and Association

Updated on 02-Mar-2021 05:19:14
In this post, we will understand the differences between aggregation and association.AssociationIt can be understood as an organization of people that have a common purpose. It also indicates that they consist of a formal structure. It represents a binary relationship between the two objects that describe some kind of activity.It is a relationship between multiple objects.An example would be how consuming healthy food is related not just to a healthy weight, but to good skin, good hair, strength and being active.Association is a relationship between two classes where one class uses the other class.It is not flexible in natureThis indicates ...

Difference Between Full Virtualization and Paravirtualization

Updated on 02-Mar-2021 05:17:13
In this post, we will understand the differences between full virtualization and paravirtualizationFull VirtualizationThis process was introduced by IBM in the year 1966. It is considered to be the first software solution for server virtualization. It uses binary translation and a direct approach method.In this, the guest OS is fully isolated using the virtual machine from the virtualization layer and hardware.Examples of full virtualization include Microsoft and Parallels systems.The virtual machine permits the execution of the instructions in addition to running the unmodified OS in a completely isolated method.It is considered to be less secure in comparison to paravirtualization.It uses ...
