Hello, Codeforces!! Many people ask for the best text editor for the programming contest. So, according to me vim is a great tool for competitive programming. It is not very comfortable to use it at first but after some time you will feel it is the best text editor ever made. So, I am going to help setup VIM(for windows) and make is ready to use for competitive programming.
WHY VIM??
I suggest, just try vim and you will get to know. But, if you are curious you can refer: https://medium.com/@fay_jai/what-is-vim-and-why-use-vim-54c67ce3c18e
You can download vim from https://www.vim.org/download.php, just download the Self-installing executable file, install it by keeping all the settings default.
Now, just launch Gvim from the start menu and you will enter a page where you would not be able to understand much but don't worry I am here to help you.
At the start, you will be in normal mode, just type :e ~\desktop\main.cpp, this will create a new file on your desktop(or if it already exists it will open it). To edit the document you have enter into insert mode(by pressing "i" key on your keyboard).
Initially, you will see a very ugly text.
But it can be improved an will look like this
For this, you have to make a _vimrc file in your home directory.
This is my _vimrc file, you can copy mine or can make your own...

Save this file by going into normal mode and typing :w, then type :source % and select your desired font.
You should also have git installed, to install plugins.
Now, you are almost done just follow some simple steps from this link(to install some useful plugins for visuals) https://github.com/VundleVim/Vundle.vim
Again type :source %, and you have the best setup for programming. Also, you can compile and run your file by just pressing F5.
You can also comment if you have any doubts. THANKS!!!
