Dish Duty

Dishes arrive in bursts while you wash from the top of the pile. Dinner rush chaos! 🧽

You get events — arrive:3 (that many dishes join the pile) or wash (top dish washed; washes always valid). Print one line: washed <total washed> left <pile size>.

Example:

Input: events = ["arrive:3", "wash", "wash", "arrive:2", "wash"] Output: washed 3 left 2

The pile grows to 3, two washes shrink it to 1 and score 2, arrive:2 grows it to 3, and one more wash shrinks it to 2 and scores a 3rd wash — 3 washed total, 2 left.
