One of the major factor if competitive programming is “Speed”. Two people solving same number of questions can have major rank difference. Every minute counts! Unfortunately I had to learn this the hard way.
So in order to increase your speed in CP contests, it is very important you are coding in right environment and using right tools.
I have made a video on how you can set up perfect CP programming environment using sublime text 3 and C++17 on Windows. Even if you compete in other languages, I would still urge you check out my latest YouTube video where I setup the above mentioned environment from scratch.
I hope you will enjoy it!
