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

Repair the Java trace function's base case and recursive argument. Run trace(3) and print the collected words as one comma-separated line in this exact order: enter 3, enter 2, enter 1, stop, leave 1, leave 2, leave 3.

enter 3, enter 2, enter 1, stop, leave 1, leave 2, leave 3

What a finished answer prints, from the lesson. Nothing has run yet — press Run and this is replaced by your program’s own output.
