## 🛠️ Tools & Scripts
|
||||
- `create_missing_notes.sh`: Automatically creates missing note files for solved problems
|
||||
- `update_difficulties.sh`: Manage problem difficulties dynamically without hardcoding
|
||||
|
||||
### Script Usage Examples:
|
||||
```bash
|
||||
# Create missing notes for new problems
|
||||
./create_missing_notes.sh
|
||||
|
||||
# Add difficulty mapping for a problem
|
||||
./update_difficulties.sh -a 1 Easy
|
||||
./update_difficulties.sh -a 4 Hard
|
||||
|
||||
# List all difficulty mappings
|
||||
./update_difficulties.sh -l
|
||||
|
||||
# Update all note files with correct difficulties
|
||||
./update_difficulties.sh -u
|
||||
|
||||
# Remove difficulty mapping
|
||||
./update_difficulties.sh -r 1
|
