Solution: Task Scheduler
Explore how to determine the minimum CPU intervals needed to complete tasks with cooling periods by tracking task frequencies. Understand how to schedule the most frequent tasks first, create idle slots, and optimize the task sequence for efficient execution in coding interviews.
We'll cover the following...
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.
