The problem being contributed must either be a simple **file** (**Eg.** [`kruskal-algorithm.cpp`](https://github.com/MakeContributions/DSA/blob/main/graphs/c-or-cpp/kruskal-algorithm.cpp), [`linear-search.java`](https://github.com/MakeContributions/DSA/blob/main/searching/java/linear-search.java)) or a more complex **directory** ([`palindrome/`](https://github.com/MakeContributions/DSA/tree/main/strings/rust/palindrome)). This is a unit `problem`.
|
||||
|
||||
The directory tree has the following convention of `category/language/problem`, where `category` is the topic or category of the problem being contributed (**Eg.** `strings`, `sorting`, `linked-lists` etc.), `language` represents the language code of the problem (**Eg.** `c-or-cpp` for C/C++, `python` for Python, `java` for Java etc.), and `problem` is a conforming name to the problem (**Eg.** `linear-search.cpp`, `palindrome`, `queue-linked-list.cpp` etc.)

- The name should be in lowercase. (**Eg.** `palindrome/`, `binary-search.cpp` etc.).

1. Create a new folder and an index for it inside (a readme, `README.md` file).
|

2. To each new index file, write the readme with your `problem` in it ([Markdown Documentation](https://guides.github.com/features/mastering-markdown/)).
