This repository is made for those who are looking for a place to make their first Pull Request for the Hacktoberfest 2020 event. You can add your own solutions to LeetCode problems found at https://leetcode.com/problemset/all/ into this repository.
Press the Fork button at the top-right corner of the page
Create a local clone of your fork by running the git clone command. Replace the <username> in the path with your own GitHub username
git clone https://github.com/<username>/Hacktoberfest-2020-LeetCode-Problems
Navigate to the folder of your local clone of the repo and create a new branch named after your GitHub username
git branch <username>
Switch branch to the new branch. Replace the <branch> with the name you set in the previous step
git checkout <branch>
Navigate to https://leetcode.com/problemset/all/ and find a problem of your liking
Create a new file in /problems for your solution to the problem of your choosing
Name the file as follows:
<username>-<problem-name>-<language>.<ext>
Where:
<username>is replaced with your GitHub username<problem-name>is replaced with the name of the problem in URL friendly format (e.g.add-two-numbers)<language>is replaced with the programming language used to solve the problem<ext>is replaced with the proper file extension for the language you chose
Add the following comment in the beginning of the file
/**
* Solution to <problem-name> at LeetCode in <language>
*
* author: <username>
* ref: <problem-source>
*/
Replace the reference <problem-source> with the URL of the problem (e.g. https://leetcode.com/problems/add-two-numbers/)
Solve and submit the problem at LeetCode. This is where the magic happens
When your solution passes all the tests at LeetCode, copy and paste the working solution in the file created previously, right below the required comment in the beginning of the file
Example solution for Two Sum problem in C#:
public class Solution {
public int[] TwoSum(int[] nums, int target) {
for (int i = 0; i < nums.Length; i++) {
for (int j = i + 1; j < nums.Length; j++) {
if (nums[i] + nums[j] == target) return new int[2] { i, j };
}
}
return null;
}
}Stage your changes in git by running the following command
git add .
Commit the file to the local repository. Replace the <filename> and <ext> accordingly
git commit -m "Add <filename>.<ext>"
Finally push the local changes to your forked repository in GitHub. Replace the <branch> with your branch name
git push origin <branch>
Navigate to your forked repository on GitHub, and press the New pull request button in the Pull requests tab
