So Today, Somehow I able to set up my vim(vi Improved) for my Competitive Programming Journey! it actually took my whole day so I don't want that you also f'''k up your mind . just chill here we go.:-
p.s:-I'll be using Linux as my OS!
installing:- Sudo apt-get install vim
:- Sudo apt-get install g++
update:- sudo apt-get update
now there is a ".vimrc" file in your home directory.
if there is no such file simply make a new one named ".vimrc" in the home directory.
edit it with this code given below:-
AND DONT TRY TO FULLY UNDERSTAND IT IF YOU ARE USING VIM FIRST TIME

Now you are all set! hope it will help you a lot!
mostly we will use 2 modes of VIM 1. Command & 2. INSERT
Press i to be in insert mode & esc to exit!
Easily write your Cpp code in INSERT mode and In command mode :F8 type it and your file will be compiled again in command mode :F9 to run your file.
ADios ME AMigos!
