⚡️ Speed up function sorter by 56%

Here's an optimized version of your program.  
**Your code uses bubble sort with unnecessary recomputation of `len(arr)`. Instead, use Python’s built-in sort (which is in-place and much, much faster).**  
If you want to preserve the manual sort for educational purposes, at least minimize attribute and function calls by keeping the length calculation outside of the loop, and **exit early if no swaps were performed** (classic bubble sort optimization).

But, for runtime, the built-in sort is best. Since your function returns the sorted array in-place, this is a drop-in replacement.

**Fastest version (use built-in sort):**

**If you want to keep a manual implementation with loop optimizations and swap-detection:**

This **avoids unnecessary passes** and decreases the inner loop range as elements bubble up.

---

**Summary:**  
- Use `arr.sort()` for best speed in production.
- If you must show sorting logic, use the manually optimized Bubble Sort shown above. 

Both return the array as before and print the same messages.
