1. To create a file using terminal :
Syntax:
In Mac:
touch <file_name>

On Windows:
type nul > <file_name>

                                  In Mac

touch code_improvizer.py

                                 In windows

C:Users\leo\projects\code_improvizer>  type nul > code_improviser.py

You can check the version of the virtual environment installed by typing the following

C:Usersleo>  virtualenv --version 

2. To create Virtual Environment navigate to the folder where you wish to create Virtual Environment and type:
Syntax: python -m virtualenv <name-of-the-virtual-environment>
or
virtualenv<name-of-the-virtual-environment>

C:Usersleocodingutilities>  python -m virtualenv venv 

                            OR

C:Usersleocodingutilities>  virtualenv venv

2. To Activate the Virtual Environment type [specific to Windows (Not for MacOS)]:
Syntax: .<name-of-the-virtual-environment>Scriptsactivate.bat
or
.<name-of-the-virtual-environment>Scriptsactivate

C:Usersleocodingutilities>  .venvScriptsactivate.bat

                           OR

C:Usersleocodingutilities>  .venvScriptsactivate

        pyautogui.FALLSAFE = False
        pyautogui.move(0,2)
        time.sleep(58)

Given an UNSORTED integer array, find two any two non-overlapping pairs having the same sum.

Sample Input:

[1, 7, 9, 3]

Output:

1 9

7 3

Explanation:

They both sum up to 10
