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 ...

ZCO during exam

How many times are you allowed to submit a program? Will you be able to check if your program works for all the test cases and work on it again if it doesn't satisfy all the test cases?

Correct. At the same time it's possible to consult with domyhomeworkonline.net before further attempts if you notice your pattern is wrong but you don't know where exactly.

Is there a tutorial on testing our code? So as to avoid getting set back by a silly mistake?? Also will we have feedback during the exam for INOI?

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...

yes it will. I previously used to code in JAVA. But in IOITC You will face LOT of problems with it. So shift to C++.

Mainly because java is slow.. so even o(n) solutions...

Recursion vs Iteration

There are two fundamental strategy to solve a problem :

Top-Down Approach (Recursion)
Bottom-Up Approach (Iteration)

I am kind of Iteration type of a guy. I find it more easier to implement than Recursion. But maybe because I have always solved most of the problems using Bottom-Up strategy.

So I was wondering, what are the advantages as well as disadvantages one has over the other and vice versa ?

Also, is it possible to solve every question using both the strategy ?

So, the iteration would be better in Competitive Programming due to low Time-Complexity and low Space-Complexity. I guess ...
