How to contribute ?

Have a look at open issues, they contain the list of algorithms/DS we plan to be implemented.
You can also create a new issue for an algorithm that is not in the list.
Fork the repository.
Clone the repo. to your local system.
Add the algorithms/codes that you want to contribute (and properly rename you algorithm/code, also if possible keep in the respective folder)
Make another Development branch. (Apart from main branch).
Open the pull request.
Resolve conflicts ( if any ).
Wait for the pull request to be approved.

Code I expect (for everyone):

Add relevant comments explaining what the code is all about (if possible write the Time and Space complexities)
It should be properly formatted and indented
Please use proper naming for variables, do not use i,j,k,x,y,z. The variable name should be self explanatory.
Use proper names for your files.
Do all your changes in your forked repository branch and not in master branch untill asked.
I will reject any pull request which looks like spammy or just to have +1 in the counter, so contribute quality code here!
As per guidlines of Hacktoberfest, I will not merge any plagrised code or any type of fishy code.
