CODE DRILL 2 · RUN ONLY

Write it, run it, read the output

This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.

TASK

Implement optimized Bubble Sort for the array [8, 5, 1, 4, 2]. Shrink the comparison boundary after each pass, stop after a pass with no swaps, and print the array after every completed pass.
