If you want to add a random thing you made, make a folder for random, make a folder for the language used and name your file starting with your user name. ex "yourusername_random.cc"
ex: make a folder for search make a folder for binary search make a folder for the language used submit your file with your username in the front "yourusername_binarysearch.cc"
Make sure that your code looks like this at the top:
/* AUTH: username https://github.com/username
* Description of what you are doing/attempting.
* Explain how it works to help others learning to program if you have time.
*/
If someone already made a file for the same thing you wanted to in the same language. It's ok to make a new one! Just make sure that for all your files, your name prepends the rest of the file name.
