| Your PR didn't pass our validation checks. Here's what went wrong and how to fix it: | |
| ### 🔍 Common Issues: | |
| **1️⃣ File Naming Convention** | |
| - **Problem:** File names don't follow our standards | |
| - **Fix:** Use descriptive names like \`binary_search.cpp\`, \`merge_sort.py\` | |
| - **Avoid:** Generic names like \`test.cpp\`, \`program.py\` | |
| **2️⃣ Wrong Directory Structure** | |
| - **Problem:** Files are not in the correct folder | |
| - **Fix:** Place files in \`Language/Category/file\` | |
| - **Examples:** | |
| - ✅ \`Python/algorithms/sorting/quick_sort.py\` | |
| - ✅ \`CPP/data_structures/trees/binary_tree.cpp\` | |
| - ❌ \`Python/quick_sort.py\` (missing category) | |
| **3️⃣ Missing Documentation** | |
| - **Problem:** Code lacks comments or complexity analysis | |
| - **Fix:** Add algorithm description, time/space complexity, and inline comments | |
| ### 🔧 How to Fix: | |
| 1. Check the workflow logs above to see specific errors | |
| 2. Fix the issues in your code | |
| 3. Commit and push the changes | |
| 4. The checks will run automatically again | |
| ### 📚 Need Help? | |
| - Check our [Contributing Guidelines](https://github.com/${context.repo.owner}/${context.repo.repo}/blob/main/CONTRIBUTING.md) | |
| - Review similar merged PRs for examples | |
| - Ask questions in the PR comments - we're here to help!`; | |
| } else if (workflowName.includes('Multi-Language Testing')) { | |
| errorExplanation = `## ❌ Code Testing Failed | |
| Your code didn't compile or run successfully. Don't worry - this is fixable! | |
| ### 🐛 Common Issues: | |
| **1️⃣ Compilation Errors** | |
| - **C/C++:** Missing headers, syntax errors, undefined variables | |
| - **Java:** Class name doesn't match filename, missing semicolons | |
| - **Python:** Indentation errors, syntax mistakes | |
| **2️⃣ Runtime Errors** | |
| - **Problem:** Code compiles but crashes when running | |
| - **Common causes:** Array out of bounds, null pointers, infinite loops | |
| - **Fix:** Add error handling and validate inputs | |
| **3️⃣ Code Requires User Input** | |
| - **Problem:** Code waits for user input (cin, scanf, input()) | |
| - **Fix:** Use test cases that don't require user input, or include sample data | |
| ### 🔧 How to Fix: | |
| 1. **Test Locally First:** | |
| \`\`\`bash | |
| # For C++ | |
| g++ your_file.cpp -o program && ./program | |
| # For Python | |
| python3 your_file.py | |
| # For Java | |
| javac YourClass.java && java YourClass | |
| \`\`\` | |
| 2. **Check the error logs** in the workflow run details | |
| 3. **Fix the errors** and test locally again | |
| 4. **Push your changes** - tests will re-run automatically | |
| ### 💡 Pro Tips: | |
| - Always test your code locally before pushing | |
| - Include test cases in your code to verify it works | |
| - Add error handling for edge cases | |
| - Avoid code that requires user input`; | |
