Solution: The Number of the Smallest Unoccupied Chair

Understand how to use two min heaps to efficiently assign the smallest available chair to arriving friends at different times. Learn to manage chair availability dynamically by processing arrivals and departures, optimizing time complexity with heaps to solve the problem effectively.

We'll cover the following...

Statement

At a party, nn friends, numbered from 00 to n−1n - 1, arrive and leave at different times. There are infinitely many chairs, numbered 00 onwards. Each arriving friend sits on the smallest available chair at that moment.

For example, ...
