Hitting arrow keys adds characters in vi editor

When I tried to use arrow keys in insert mode in vi editor the following characters are being inserted in the editor:

• for ↓ I get B,
• for ↑ I get A,
• for ← I get D,
• for → I get C.

Here is a basic trick to solve this problem

Open terminal 

If you don't already have a .vimrc file in your home directory, create one using this:

• vim ~/.vimrc

Add this line to the top of the file:

• set nocompatible

If you don't already have a .vimrc file in your home directory, create one using this:

vim ~/.vimrc

Add this line to the top of the file:

set nocompatible

Save the file and this should fix the problem for you. :)

If you face problem in saving 

press ESC button and type :x! or :x press Enter 

now you can proceed with vim or vi
