Contribution Guidelines

A working Program should be pushed.
The variable name should be related to its purpose.
The program should in indented.
You should push the solution to the mentioned file.
Here's a sample how to write a code and contribute.

How to Make A Pull Request with your solution in the given file.

Go to given file where you could see the problem.
See the format of the problem and write your function accordingly. (Would help you to write a clean code.)
Click on create new file
Copy your code there and with SolutionByA.cpp [ A would be Your Name - Like SolutionByShoaib.cpp ]
After copying, click on propose new file.[ At the Bottom]
Then You'd be redirected to new page, where you need to click on create pull request.
Then you can add your comments or anything you want to tell abour you solution.
Then Click on create pull request.
You have pushed your solution to the repository.
