This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.
TASK
Complete countDown so countDown(4) prints 4 3 2 1, counts every invocation including countDown(0), and tracks the maximum number of active frames. Then print the total invocations and maximum active frames.
OUTPUT
Sample4 3 2 1 Total invocations: 5 Maximum active frames: 5
What a finished answer prints, from the lesson. Nothing has run yet — press Run and this is replaced by your program’s own output.
