This repo inhouse the code that take's user's all the solution from Leetcode and transfers them to Github my solutions using this repo will be found here : https://github.com/heemankv/LeetCode-Solutions.git

Usage use .env in root folder that will have

COOKIE = abcdef

extract cookie from network tab

Using the Feynman technique

Feynman Technique

• Choose a topic
  • Get something you want to learn
• Do initial research
  • Define the scope you want to work with
• Explain it to a 12 year old
  • Document it in a paragraph as to what you want to do
• Reflect, Refine and Simplify
  • build something fast and simple completely
• Organise and Review
  • Now find someone to review it and help you make it better

Choose a Topic: Get all the codes present on leetcode to github in a date based commit fashion.

Do initial research 1) Leetcode Graphql (https://leetcode.com/graphql/) will be needed to fetch the list of codes and code snippets. 2) .md + .cpp file management will be needed to club all the data together in a single file and then push it. 3) Github git bash commands will be needed to commit code based on date received from Leetcode.

Assumptions It will be a single time run service. All the codes are written in cpp. User is logged in to git on machine's cli User provides with Leetcode CSRF token

New Tech played with Extensive file management Graphql api Github commit flow

Configs needed Github repo r/w access

Order looks like so: Upon request Fetch of user's solved question list from Leetcode For Each solved question we need: Question Id Solution Question Solution date and time This acquired data will be committed to Github using git bash based on predefined dated.

Result: Github should have a repo which will have all the solutions stored as folders having question_id.cpp and question_id.md question_id.cpp consists of code. question_id.md consists of meta data around it.

Explaining it to a 12 year old I want a single place which has all the codes written by me stored. I want these codes from Leetcode to help increase the language spread on my Github.

Question ? Which Language Let's take a challenge and do this in goLang !

Updates and Findings:

1. Initially idk why I thought that it would be a rest api, actually it will just be a go script, maybe having some bash with it, nothing else
2. "lang": 0 -> for a graphql query to leetcode cpp is lang : 0
3. for the user's solution query we are already getting timestamp of submission, this can help us is making timestamp for user commit on Github
4. Will have to run prettier before committing the codes.
5. Issue #1, need a repo created before the oldest time-morphed commit. because commit tree will be started from there and that is not in our hands to fake. -> https://github.com/heemankv/LeetCode-Solutions.git SORTED
6. Issue #2, SORT QUESTIONS BY DATE solved, so that commit graph can be made in a chronological manner !
7. Issue #3, How to commit
   1. Either assume that the user is connected to bitBash , and run bash scripts from terminal -> https://stackoverflow.com/questions/25834277/executing-a-bash-script-from-golang
   2. Or do go-git auth process -> https://stackoverflow.com/questions/61677396/pushing-to-a-remote-with-basic-authentication
   3. Need to do a "chmod +x pathToScript" for all the
8. Did not account for html coming from graphql coming from backend assumed it to be a simple string, now might have to make a html to markdown parser or use an online tool.
9. Do have to ensure to run prettier after each folder creation / before each commit !

Queries : Managed inside POSTMAN, ensure to make is publicly available after removing personal info like CSRF token and so

Update: 31st July 2023 Although my code is ready till it's last 95% I am unable to understand why it's failing for this : xD this was a simple problem wherein my solution on github was actually null and my type assertion was failing for the same, handled using assertiong validation , could have used proper error handling

Final Thoughs This is my first code in GoLang, judging by that, It's pretty decent. I could have made the code more error proof. Scalibility issues:

1. it takes codes from leetcode edit code tab rather than all submitted solutions tab this design flaw let the code not get solutions for approximately 40+ questions it should have taken the last submitted solution
2. a usual practice in DSA doesn't end at leetcode, it expands to other platforms like gfg, hackerrank, codechef, codeforces, etc this code is not scalable to other platforms
3. the code makes two seperate calls 1 for question decription the other for code, this can be clubbed into one call if we use the graphql api properly

Let's Keep Building !!!
