Leetcode 1107. New Users Daily Count
Given a table of user activity/dates, determine how many users are "new" each day by identifying each user's earliest activity date and aggregating counts per day. The key challenge is deduplicating multiple events per user (choosing the first date) and producing a per-day count (including days with zero new users if required).
