Hacktoberfest Contribution Guidelines

Welcome to the Hacktoberfest repository! 🎉 We're excited to have you participate and contribute to open-source projects. Please follow the guidelines outlined below to ensure a smooth and rewarding experience for everyone.

📜 Contribution Guidelines

  1. Contribute New Problems Only:
    You can make a pull request only for a new problem statement. Solutions to already existing problems will be marked as invalid and rejected.

  2. Problem Source:
    Problems can be taken from any reputable coding platform like CodeChef, CodeForces, LeetCode, HackerRank, etc. Please ensure you mention the source in your problem file.

  3. File Naming Convention:

    • The file name should be the exact name of the question.
    • If the question name contains spaces, replace the spaces with underscores (_).
    • Follow abbrev. CF - CodeForces, CC - CodeChef, LT - LeetCode, HR - Hackerrank, GFG - GeekForGeeks, etc
    • Add the appropriate file extension based on the language used:
      • For example, if the question is "Score More Buddy" on Codeforce, rename it as CF_Score_More_Buddy.cpp, CF_Score_More_Buddy.java, CF_Score_More_Buddy.py, or CF_Score_More_Buddy.c based on the language of your choice.

  4. Adding the Problem Link:

    • At the top of your code, include a link to the problem statement as a comment.
    • This helps reviewers validate your solution and ensures the contribution adheres to the problem's context.
    • Example: 
      // Problem Link: https://www.hackerrank.com/challenges/score-more-buddy/problem

  5. Avoid Irrelevant Submissions:

    • Any irrelevant contributions will be marked as spam and reported.
    • Examples include multiple trivial changes, unrelated files, or repetitive solutions to simple problems.
