Any One Can Code! Dive into this awesome world


The motivation for this post are many . I will mention a few.

  • Startups have got smart and they need smart people. They have developed “ShowMeYourCode” attitude. And this is an awesome approach.
  • Coding regularly helps build confidence. Which normal people lack.
  • And finally, it’s AWESOME!

Coming to point!

I will provide few curated list of links which will help you to atleast get your hands dirty.

NOTE: Not a accurate list so suggestions welcome!

Problem Statement:

I want to learn algorithms and DataStructures so that it helps me build some confidence.

Step 1. Start with basic algorithms. (I have listed the links priority wise)

Step 2: When you have build a tad amount confidence then start with

Step 3: Advance to some more tough algorithms from (Step 1) according to your convenience and comfortability. IMPLEMENT THOSE!!!!

Step 4: Solve more tough problems on Online Judge from STEP 2.

Step 5: Compete in competitions on judges from STEP 2.

Step 6: Iterate! Iterate! Iterate

Step 7: Iterate more more and more!

So this will be my approach.

Few tips:

  • Please take a pen and paper and sit. Don’t rely on doing calculations like a Sherlock
  • Persist to get AC. A problem is not tough till it doesn’t depresses you!
  • Read Code and read more of smart coders for all problems
  • And finally, this is a process of not 1 day or 2 day but till the time you can solve a tough problem in one go.

Few Important links:

Programming languages:

  • Python ( My personal fav! Don’t know which language to choose. Blindly go for this . See below for tutorials related to this)
  • C++ ( Smart people’s award goes to this)
  • JavaScript (Web learning a bonus with this)

My Favourite Python helpful tutorials

Complexity of data structure operations:
Algorithm Lecture Videos:

Advance Preparations:


Few Other links:

See this for more details

So, Here is an exhaustive list of a lifetime preparation. Do this and I will register your name as “Iron-man” officially in algos and ds ( I am serious)!

Happy Coding!


HackerEarth Solutions Scraping !!

So for my first post I am choosing a simple yet a good mini-mini project.


I wanted to post all my HackerEarth solution to Github. But I had arround 500 problems solved at this time so it would have been tedious if I would have done it manually. So, I thought of scrapping all my solutions and posting it on Github.

How it is Different?
        It is not a normal scraping where you can use BeautifulSoup and then scrap data normally (At least I din’t find out , so please bear with me :)). Here when you open HackerEarth , two things were creating a hurdle for me.
1. Data was loaded dynamically using AJAX script

2. When you scroll down for 5 times you will see a “View More” button (provided You have solved enough problems :P) . So you have to click it to load more data. So this stuff required automation.

As you can see I did not find any BeautifulSoup method to scrape dynamic data so I decided to make and share this project.

Stack Used?
As this required automation so I have used Selenium ( Python API) with Firefox driver to automate the process. I dont know why but chrome driver was a huge pain and did not help (at least for me) . So learning about the right stack before pondering upon the code is a bonus takeaway from this project for me.

**Here is the Code**

Pretty self explanatory! You can pull , raise issue, fork ! Do whatever you want to do but do!

Please let me know if you have got any issues or comments!

Please feel free to comment!

My First Post!

Hi all,
I am starting this post to help other coders and developers and in general CS people or for that matter any one interested in learning fundamental/intermediate/advance concepts on computers , algorithms , data structures , or any other interesting facts.

The main purpose of this blog is that I would like to share my knowledge and also I would like to learn from you all guys. I believe in keeping knowledge as open -source as possible because that’s how we excel.

This is my first kind of experience so please bear with my mediocrity. But I will try to raise the standards by each and every blog , in fact each and each every comment.

Lastly I would like to say to welcome to all the visitors and just know one thing
 “The fool din’t know it was impossible hence he did it”
