Solution: The Number of the Smallest Unoccupied Chair

Understand how to implement a heap-based algorithm to assign the smallest unoccupied chair to arriving friends at different times. Learn to manage chair availability dynamically using two min-heaps for efficient scheduling and retrieval, and analyze the algorithm's time and space complexity for optimized performance.

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, ...
