Solution: Task Scheduler

Explore how to schedule CPU tasks with cooling intervals by analyzing task frequencies and arranging them to minimize idle time. Understand the method to compute the minimum CPU intervals required to complete all tasks given constraints on cooling periods and task repetitions.

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.

Constraints:

  • 1 1 \leq ...
