Best Platforms for training

How to contribute

1. Fork the repository
2. Do the desired changes (add/delete/modify)
3. Make a pull request

When contribute

1. If there is no solution or explanation to a problem in the main branch.
2. Generally codes are in C++ if your solution is in other langauge.
3. If your solution is asymptotically faster than the one in the main branch.
4. 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.
5. 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.
6. If you would like to make any positive change to the resources content.
