Solution: Task Scheduler
Explore how to optimize task scheduling with cooling period constraints by counting task frequencies, arranging them to minimize CPU idle time, and calculating the minimum intervals needed. Understand the algorithm to solve the Task Scheduler problem efficiently with fixed space and linear time complexity.
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.
