Interview Prompt
We keep a table of repository commits, each stamped with its author and commit date. Looking only at the most recent stretch of activity, find the ten authors with the most commits, and return each with their commit count, most active first.
Summary
Recent activity is the only activity that counts. Name the busiest hands.
How This Interview Works
