/*
This program extracts all integer values from a mixed string
and sorts them using the language's built‑in array sorting mechanism.
It demonstrates:
- clear separation of concerns using functions
- efficient number extraction using regular expressions
- dynamic storage using arrays
- fast numeric sorting with sort()
