Helper Utilities

next.sh - Exercise Download Helper

A convenience script that automates downloading the next exercise:

• Scans this README.md to find the first exercise marked as in-progress (🔄)
• Checks if the exercise already exists locally
• Downloads the exercise using exercism CLI if not present
• Uses the configured exercism workspace path

Usage:

./next.sh
