  • First steps:
    • Clone this repository and create a new branch with convenient names like the followings:
      • add-problem-name
      • add-problem-name-approach-2
      • fix-problem-name-python-sol
      • fix-problem-name-readme
    • When you are done with your code open a new PR to the master and describe in your PR why you creating this PR:
      • Adding Problem Name (as a link to the problem) solution in [Chosen language].
  • Add a new solution for an existing problem:

    • You need to update the existing problem README.md file with your solution.

    • The file will be organized in this hierarchy:

      • Approach 1
      • Approach 2
      • ...etc

    • So check what is the level of your solution and add it:

      • Approach 2:
        your solution

    • If you add a new solution without explaining it do your best at least to add the time & space complexity for it or pseudocode.

    • If you can not fit the previous step you can ignore the hierarchy of the Approaches and add your solution this way:

      • Another implementation in the language you writing in. (Make sure it is a URL to the solution.[js,java] file)

    • Let's say if your new solution is in a language already exist in the repo like Solution.py you can edit this file by adding another function lets say the solution in function called sum2numbers(x,y) add new function sum2numbers_2(X,Y), I would prefer doing it this way otherwise you can create a new file called Solution2.py.

    • If your solution the same idea as Approach 1 for example but in different language you just need to add as mentioned above and update the problem README file with a link to your code:

      • Solution in java as url of course to Solution.java.
  • Add a new solution for a new problem:

    • So, let's say the problem belongs to the 30-Day LeetCoding Challenge so go to it is a directory and create a new folder with the problem name new-problem add a URL to that directory in the README.md if it is week not there add it as well in the same way as the existing ones.

    • Then, under the new-problem directory create README.md file and Solution.[chosen-lang].

    • Write the README.md file in the same way as existing one's header with the problem name as URL to the problem location on Leetcode, then add Approach 1 title then add your solution follow the steps as in the above section (Add a new solution for an existing problem).

    • What if it is a random problem from Leetcode problem, create a new directory for this new problem in the main folder leetcode-problems/the-new-random-problem and add it in the main README.md as well as URL to this new directory for sure, the structure of the the-new-random-problem must be the same as above.
