Theory of Programming is a very helpful website that helps you in understanding a wide range of programming concepts. There are many posts on Data Structures, Algorithms and the Java Programming Language which explain the concepts with vivid explanations, well-drawn diagrams and also come with the actual code of concept.

Theory of Programming also has posts on solving competitive coding questions which are based on data structures and algorithms discussed in the website. These help you not only to be a hero in your classroom but also a legend in the coding websites such as CodeChef, SPOJ, etc.

Hello people…! In this post I will talk about another single source shortest path algorithm, the Bellman Ford Algorithm. Unlike Dijkstra’s Algorithm, which works only for a graph positive edge weights, the Bellman Ford Algorithm will give the shortest path from a given vertex for a graph with negative edge weights also. Due to this, …

Tree Data Structures

Every programmer needs a suitable data structure to compute some complex function or to do a time-taking task quickly. In this post, I will explain the Binary Indexed Tree (BIT) data structure also known as the Fenwick Tree in post-soviet countries. This data structure is very easy to code in competitions. So, a programmer who …

please provide a editorial on kmp algorithm.

please make a tutorial on suffix tree..

Sure…! We will try to post a tutorial on suffix tree in the near future 🙂

when you click on something in some cases cursor not appear , you need to fix that thing

This website was shifted from WordPress.com to a self-hosted one… So errors do creep in…. Can you be more specific so that I can deal with this..?

Nice job done sir. (y)

Thank you..!! 😀

This is really nice vamsie

Thanks a lot….!! 😀

hi, can u provide notes on hashmap, please…

I’ll try 🙂

great work Vamsi.. 🙂

Thank you Nitesh…! 🙂 😀

Good work Vamsi…..Here are a few suggestions-

1. For every topic you have covered just at the end give few links of the question may be from spoj, codechef, codeforces etc where people can practice after reading from the topics. This is because as the case of programming is concerned reading only or understanding will not help, you have to do a great deal of practice. Just make sections like beginners problem, advance and professional problems or something like that under each section.

2. Make a separate forum where people can post questions about different topics or questions and not only you others can also give their answers. It would help to bring the programming community and different coders together to your site.

3. Make a separate section for interview corner. Here write interview experience of people of different companies.

4. Make sections for Java, C, C++ basic concepts.

5. Maybe the name of books you want to recommend.

6. Output/MCQ questions or Quiz kind of thing of the topics studied.

Please don’t feel offended, but there are a lot many sites where you can find this stuff. You have to make things different from them and even better to attract people towards your site. You can take this journey of your to great levels.

Once again great work and just please don’t feel bad by my words. The above are just suggestions. You are free to implement any subsets of these including the null set.

Haha…! I was actually looking forward for suggestions such as these Vipul sir. As I am still young and I don’t have as much exposure as you sir. I am very glad you gave me these suggestions sir. And they are pretty cool too, sir. But they’ll take time. Eventually, I will surely implement them, sir, because you pin-pointed the drawbacks of my blog very accurately. Thanks a lot for your suggestions sir, they mean a lot to me…! ☺

Yes it will take time. So it is better to ask your batch-mates who are good in respective topics to write about some topics and give it to you in the required format. And then you put it on your site and also acknowledge them at the last of the post by writing something like- Thanks to Mr. xyz for contributing/helping for this post/topic. Moreover make a different section where you put the name of all those who have contributed so that you bring the programming community together. In this way they would also show interest in promoting your site as their name appears on it and also you will be able to quickly develop the website. Again you are free to implement any subsets of these including the null set.

That’s a great suggestion for developing the blog Vipul sir…! ☺ I will surely see what I can do. Thanks for the suggestion sir..! ☺

great work Vamsi !! keep it up (y)

Thanks a lot Keerti…!! 🙂

super ra . its very nice and also much helpful 🙂 🙂 all the best and hoping to see more like this from you . thumbs up 🙂

Nice blog, please keep adding more content. One recommendation, it would be more friendly to use this blog if the flow diagram above would take to the relevant sections directly when clicked. Ex: Clicking on ‘Learn New Data Structures’ directly takes us to the data structures table of contents.

Thanks a lot for the feedback, sir. It is an excellent suggestion too ! That would make a great feature. I will surely look into it…! Have a nice day !
