- Fork the repository
- Do the desired changes (add/delete/modify)
- Make a pull request
- If there is no solution or explanation to a problem in the main branch.
- Generally codes are in C++ if your solution is in other langauge.
- If your solution is asymptotically faster than the one in the main branch.
- If your algorithm is of the same time complexity but with reduced code size. In this case, comment out the original solution and make a pull request with your solution.
- If you have another method of solving the problem which is asymptotically slower than the original method then, comment your solution in the main file and make a pull request.
- If you would like to make any positive change to the resources content.
Constructive criticisms or code reviews of any kind are very much welcome.
