Solution: The Number of the Smallest Unoccupied Chair

Understand how to use min heaps to manage chair assignments as friends arrive and leave, ensuring the smallest chair is always allocated efficiently. Explore sorting, heap operations, and a clear algorithm to solve the smallest unoccupied chair challenge, improving problem-solving skills in coding interviews.

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.
