Programming

Personal and Skill Development

Develop your coding skills, learn a new language or prepare for campus placements and job interviews, you can do it all with these awesome courses.

This course provides you an insight into easy & medium level Codechef problems. The aim is to slowly increase the level of beginners in competitive programming through this series. There is an in depth discussion of some really important concepts like Number Game & Euclid's GCD Algorithm etc.

Data science is an exciting discipline that allows you to turn raw data into understanding, insight, and knowledge. The goal of this course is to help you learn the most important tool in R that will allow you to do data science. After completing this you will have the tool to tackle a wide variety of data science problems using the best parts of R.

R Programming: Introductory Course in Data Science (Hindi)

In this course, Dhiman Mayank has discussed non-linear data structure. He has covered trees, operations on binary search trees, tree deletion, interview questions on trees, AVL trees with insertion, red-black trees, segmented trees, introduction to graphs, and graph representation extensively.

Introduction to Non-Linear Data Structures

In this course, Akshay Kishor Chauhan has discussed Basics of Linux. He has extensively covered the introduction, VMware, Ubuntu, Wildcards, Linking, file manipulation, pipes In Linux, sorting in Linux etc.

The students will have a deeper insight of the data structures, linked lists, insertion and deletion of nodes. It covers all the important theoretical concepts and intuition behind the data structures, making it the building blocks for any programming enthusiast. The collection then deals with Stacks, Queues, Recursion Intuition, Binary Trees and Inorder Traversal. We see that Programming is nothing but writing functions/methods to manipulate data. The last part of the collection focuses on an introduction to the Graph, Matrix Representation and understanding Hashing. This collection will give students a complete understanding of the data structures and how and when they should be used.



In-depth And Comprehensive Detail On The Study Of Basic Data Structures

This course deals with the Abstract Data Type Queue and its implementation. In these series of lessons, we will try to do an in-depth analysis of queue and its implementations. The course also deals with solving competitive programming questions based on queue along with some typical questions asked in an interview.

Introduction To Queues

In this course, Pratiksha Tripathi discusses the features of Angular JS. The course will be beneficial for anyone who wants to learn the basics of Angular JS.

AngularJS for Beginners

In this collection, we go through the problems of Codeforces Round #371(Div-2), discuss the methodology to approach the problems and the roadblocks that one might counter while solving them. Problems A, B are cakewalk problems that require some logical thinking and minimal coding. Problem C has a straightforward solution and requires some hashing mechanism. Problem D is a fun, interactive problem that requires us to exploit the monotonic aspects of the problem to frame a solution.

In this course, Dhiman has discussed Greedy problems and its uses. Here, he has discussed Fractional Knapsack, Kruskal's and Prim's Algorithm, Page replacement using Greedy, Vertical Order tree print.

Introduction to Greedy Algorithm

In this collection, we go through the problems of Codeforces Round #370, discuss the methodology to approach the problems and the roadblocks that one might counter while solving them. Problems A,B are straightforward.  Problem C demands some observations, while D requires experience with solving similar problems.

This is a beginner level course on graph theory and its application. In this course, Adarsh has tried to explain graphs from scratch and explained the basics of graph theory. This course contains 8 lessons. In first 7 lessons he has discussed graph representation and its traversal techniques and in the 8th lesson Adarsh has discussed a famous beginner level problem(BUGLIFE) from SPOJ and implemented it in C++.

Introduction to Graph Theory

The course is about exploring one of the most popular tree implementation in competitive coding –Segment Tree. This course provides you with a hands-on experience about segment trees and its application in varieties of the question asked in competitive coding events. With a good knowledge of segment tree, you are qualified enough to cross that barrier of solving a moderate to difficult range query based question in which a brute force implementation would always land up in Time Limit Exceeded status.
