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.

This is a course which will introduce you to the world of competitive programming. This course contains every basic thing which is required for beginners to get started in this sport.

Getting started with Competitive Programming in Codechef - Part 1

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.

Getting started with Competitive Programming in Codechef - Part 2

This series aims to take your programming to the next level. The series focuses on aspiring programmers who aim to be better at coding.

Hackerearth Inc.

Get started with Computer Programming in these very well explained lessons. The first two lessons focus on solving problems so that one gets a hang of programming and also provides guidance on the requirements and expectations of a programming problem. It will also help in learning as to how to test one's code via custom I/O. The further lessons discuss introduction to an array- 1-D Array, Multidimensional Array, Types of Strings- CStyle String, C++ Std Class Strings and also learn how string classes are to be used. One would also learn about Standard and File I/O and also study the toolkit (STL) available and discuss how one can utilize the provided inbuilt containers.
