TheAlgorithms-C/leetcode

📚 Contributing 📚

We're glad you're interested in adding C LeetCode solutions to the repository.
Here we'll be explaining how to contribute to LeetCode solutions properly.

💻 Cloning/setting up the project 💻

First off, you'll need to fork the repository here.
Then, you'll need to clone the repository to your local machine.

git clone https://github.com/your-username/C.git

After that, you'll need to create a new branch for your solution.

git checkout -b solution/your-solution-name

📝 Adding a new solution 📝

All LeetCode problems can be found here.
If you have a solution to any of these problems (which are not being repeated), that's great! Here are the steps:

1. Add a new file in leetcode/src with the number of the problem.
   • For example: if the problem's number is 98, the filename should be 98.c.
2. Provide a small description of the solution at the top of the file. A function should go below that. For example:

/**
 * Return an array of arrays of size *returnSize.
 * The sizes of the arrays are returned as *returnColumnSizes array.
 * Note: Both returned array and *columnSizes array must be malloced, assume caller calls free().
 */

3. Do not provide a main function. Use the required standalone functions instead.
4. Doxygen documentation isn't used in LeetCode solutions. Simple/small documentation or comments should be fine.
5. Don't include libraries/headers such as stdio.h. Your file should be the solution to the problem only.

Note There was a requirement to update the leetcode/DIRECTORY.md file with details of the solved problem. It's not required anymore. The information about the problem is fetched automatically throughout the LeetCode API.

📦 Committing your changes 📦

Once you're done with adding a new LeetCode solution, it's time we make a pull request.

1. First, stage your changes.

git add leetcode/src/98.c # Use `git add .` to stage all changes.

2. Then, commit your changes.

git commit -m "feat: add LeetCode problem 98" -m "Commit description" # Optional

3. Finally, push your changes to your forked repository.

git push origin solution/your-solution-name:solution/your-solution-name

4. You're done now! You just have to make a pull request. 🎉
