Solution: Task Scheduler

Explore how to efficiently schedule CPU tasks with cooling periods by analyzing task frequencies. Learn to calculate the minimum CPU intervals needed by organizing tasks to maximize idle slot utilization and reduce total execution time.

Statement

You are given an array of CPU tasks represented by uppercase letters (A to Z) and an integer n, which denotes the cooling period required between any two identical tasks. Each task takes exactly one CPU interval to execute. Therefore, each CPU interval can either perform a task or remain idle. Tasks can be executed in any order, but the same task must be separated by at least n intervals.

Determine the minimum number of CPU intervals required to complete all tasks.
