CODE DRILL 1 · RUN ONLY
This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.
TASK
Implement top-down merge sort for the tagged array [6, 3a, 8, 2, 5, 3b, 7, 1]. Compare elements by numeric value, use half-open ranges and one reusable temporary array, and print the sorted array with each tag preserved.
OUTPUT
Sample[1, 2, 3a, 3b, 5, 6, 7, 8]
What a finished answer prints, from the lesson. Nothing has run yet — press Run and this is replaced by your program’s own output.
