Contributing

Step 0

If you are new to how to contribute to GitHub projects, don't forget to check our HOWTO guide.

Open an issue describing the contribution you want to make. Here's an example issue for your reference.

Examples of some contributions:

Adding a solution to a LeetCode problem in a particular programming language.
Adding a second solution with a different approach to a LeetCode problem in a particular programming language.
Adding relevant resources such as youtube videos, articles, tutorials that are going to help someone solve the LeetCode problem.

and so on

The project is structured as follows:

.
├── [Category]
│   └── [Problem Difficulty]
│       └── [Problem]
│           └── [Solution and Resources]
├── ...
│
...

Here, the values for

If you need to create a folder for any Category or any Problem Difficulty, make sure to name it accordingly.

As for Problem, the naming convention we are following is

[Problem Number]_[Problem Name]
Example: 1_TwoSum

Note: Problem Name should be in Pascal case

Now, in case of Solution and Resources

Solution

Solution in a particular programming language should be in a file named Solution with appropriate file extension. For example, Solution.java for Java.
You should utilize the solution template provided by LeetCode for a particular programming language and write your code in such a way that submitting your solution via pasting it in the LeetCode editor should provide an Accepted verdict.
Suppose you want to add a second solution to a problem in a particular programming language. In that case, name the file as SolutionOne with appropriate file extension.
You should be consistent regarding naming convention in your code.
You should use 4 spaces for indentation.
You should use meaningful variable names and function names where appropriate.
You should add comments where appropriate.
You should use appropriate spaces to make your code more readable. For example:

// Bad
int i=0;

// Good
int i = 0;

// Bad
if(i<10){
  ...
}else{
  ...
}

// Good
if (i < 10) {
  ...
} else {
  ...
}

Resources

Resources for each of the problems should be in a file Resources.md. If it is not already present, feel free to create one.

If you want to add a resource, make sure to:
