Q&A session

Q&A Session with Sumeet Varma

Codeforces India #1

Ended

This Q&A Session has now ended but

Sumeet may still answer new questions

Hey there! I’m Sumeet Varma. I am extremely interested in Algorithms and Data Structures and so I do a lot of competitive programming. I am also a big fan of Counter-Strike, Politics and reading random answers on Quora.

My team (FruitSalad) came 1st in ACM ICPC ‘17 Kharagpur Regionals, 2nd in Kolkata Regionals and 7th in India Finals and we have qualified for World Finals. Also, I have been Red on Codeforces and the highest rated Indian programmer on Codeforces, Hackerrank and Topcoder in the past.

Currently, I am doing an internship at Directi (Bangalore) as a part of my project for final semester at DA-IICT, Gandhinagar.

Ask me anything!

Moderator note: We are very excited to host Sumeet for a Q&A session! He has a max rating of 2515 on Codeforces and 2173 on TopCoder, and you can see the graph going up consistently over the last 2.5 years. It's time to find out more about the person behind ...

Tricks and Tweaks to code quickly and efficiently

This discussion is for expanding your array of maneuvers needed to code quickly and efficiently.

STL:

The first and most important thing that I'd like to discuss about is the C++ STL. Learning it would enable you to code up an assortment of algorithms and complicated data structures in a matter of seconds.

You can learn to use the C++ STL from the following amazing sites:

Studytonight : Contains syntax and examples for most of the STL containers and algorithms.

Sanfoundry : Shows how to implement what you've learnt in complete programs

Topcoder(Highly recommended) : This place teaches yo...

Hello Everyone!

I am Samarth Singla, studying in class XI at Delhi Public School, Faridabad.

That's to say I am relatively new to CP and would like to learn a lot from the guidance of people in this community!

I do think that it is essential to be sure that the program works for all the test cases. As well as be confident about writing dissertation abstract if you are still a student.
