Why learn Competitive Coding?
Competitive programming is one of the buzzwords nowadays and its popularity comes from regular coding contests around the world and their intensive problems which test the problem-solving abilities of participants.
It is a mind sport where few problems are to be solved under a certain amount of time and the fastest and most efficient ones make it to the leaderboard. This enhances your thinking abilities and helps you to come with efficient solutions faster.
Competitive coding provides the following:
- Enhances thinking ability
- Faster intuition for solving problems
- Trains your brain for interview and machine coding rounds
- Develops the correct aptitude to crack software developer roles too
- And of course, it’s always fun!
You can choose any language to compete in the various contest and showcase your skills to get good ranks and stars. Many top product-based companies like Google, Amazon, Facebook, etc sometimes hire from competitive coding contests. Because it becomes increasingly necessary to come up with an efficient solution to a given problem that not only saves CPU time but also overhead cost for companies.
So, if you are someone who aims for getting into the big tech gigs then acing Competitive Programming becomes a crucial step towards that goal and the Coding Ninjas Free trial course is just waiting for your first step.
Features of Free Trial
In this Guide to Competitive Programming, you will be learning a comprehensive yet curated set of problems as
- Introduction to Competitive Coding
- How to approach and solve problems in real contests
- Multiple Choice Questions (MCQ) to test your skills on important topics
- Searching and sorting algorithms and their applications (most important in view of coding contests)
- Basics of Recursion: Being one of the most important concepts and forms the basis for dynamic programming (popular topic for tech interviews)
- Time Complexity Analysis: To know you have the most efficient program or not you will require to assess your own code. The intuition of optimism through simple algorithms is the aim of this section. Know your Code!
- In language tools, you will be supported with STL in C++ videos along with support for Java, Python in PDF formats that you can easily download and go through.
- Greedy Algorithms: All you need to know about greedy problems and their approach with coding sections to test your understanding. These also contain hints to help you out whenever you need the slightest of help.
You will also have one test after the completion to test your learnings and the course will contain a total of 19 coding problems to test whether you have understood the concepts taught in the course. The videos also explain the concepts of Complexity calculations for each of the problems that will be discussed.
If you are stuck in any problem, hints are there to help you out. Still, stuck at a problem? Check out the detailed solution through this Guide to Competitive Programming and understand the intuition and concept used, so that next time you see the problem it becomes a piece of cake to solve it.
You can check out the sections which have Doubts, mentor inquiry and course pause option.
Each of these chapters has video lectures and practice problems with a dedicated code section.
You can opt for asking doubts, hints and finally a solution to a particular problem. Although if you have not solved the problem, seeing the solution will penalise your score while if you have completed the solution then you can see the solution provided by experts without incurring any penalty and optimise your code.
This course is generally for beginners and every aspect is explained with in-depth tutorials although prior knowledge of basic coding is beneficial. The fundamentals of data structures and how to apply them in problem-solving will also help you get a better overview from this course. You can take up the course irrespective of any language you are comfortable with.
- Basic Mathematics
- Fundamentals of programming
Companies that typically hire candidates with these characteristics
Top companies like Google, Apple, Microsoft, Amazon, Facebook, Netflix, etc. hire talents with high problem-solving skills. These companies also target candidates with excellent competitive coding tracks that can only be built with proper guidance and practice.
Some of these companies also hire candidates who have participated in ACM ICPC, which happens to be one of the most recognized competitive coding contests around the world, and getting a chance to even participating in the competition is a huge recognition itself.
Also, read about the preparation guide for ACM ICPC
Let me also jot down some important company-wise topics that are important to crack the interviews:
- Google: Focuses on Graph-based problems are asked quite often.
- Samsung: Trees and Binary Search tree topics along with a strong understanding of recursion are necessary.
- Amazon: likes to explore a wide range of problems including recursion, dynamic programming, graph traversals, sorting and searching problems, binary search, etc.
- Microsoft: generally doesn’t allow much support for helper libraries like STL for C++ in the machine coding rounds, hence requires an in-depth clear understanding of linked list, stacks, queues, as they have to be coded from the basics and that’s what this course will help you with too.
- Facebook: interviews focus on graph-based problems and their traversals.
Other popular competitive coding contests like Google Hashcode, Codejam, Facebook coding challenge, etc, are some of the most well-known prestigious platforms to showcase your competitive coding skills and will get a chance to be interviewed by tech giants.
These competitions provide a platform to test the candidate’s ability to tackle pressure and come up with the most efficient solution in less time. That’s what any big company will be looking for. You can practice company-wise popularly asked coding questions from Coding Ninjas free practice section CodeStudio.
Let me jot down an example of how this course will help you. Sorting algorithms are the most favourite interview questions as well as competitive coding concepts, most of the problems require some kind of sorting algorithms to make solutions more efficient.
The course content also develops the intuition of using such algorithms to a problem that otherwise will be difficult to solve and would require more time too. This course will also walk you through all the dry-running steps you would require to understand the concepts.
You can choose to pack more such tricks in your pocket by joining the paid course, as it provides a wider variety of problems with their intuitions. Each problem is explained with the concept, intuition, dry-run, machine coding such that it leaves no stone unturned to make you understand.
The paid course is also valuable for its peer learning and placement assistance feature that helps you compete and learn from your peers and also take part in the hiring challenges organised by companies through Coding Ninjas.

Frequently Asked Questions
For beginners, I would recommend Hackerrank, Codechef, as these sites are pretty easy to comprehend and provide support for most of the languages and Hackerrank also provides difficulty-based problem recommendations.
Although you can choose any programming language it is recommended to mostly use C++, Python, or Java for beginners. C++ has support for STL that is a huge support for writing codes for complex problems. Java provides support for garbage cleaning and hence reduces the chances of errors. Python syntax is fairly simple and small and hence requires fewer lines of code than others.
