Understanding the Task Scheduler Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given an array of CPU tasks, each labeled with a letter from A to Z, and a number n. Each CPU interval can be idle or allow the completion of one task. Tasks can be completed in any order, but there's a constraint: there has to be a gap of at least n intervals between two tasks with the same label. Return the minimum number of CPU intervals required to complete all tasks.

Examples
tasks = ["A","A","A","B","B","B"], n = 28A possible sequence is: A -> B -> idle -> A -> B -> idle -> A -> B. After completing task A, you must wait two intervals before doing A again. The same applies to task B. In the 3rd interval, neither A nor B can be done, so you idle. By the 4th interval, you can do A again as 2 intervals have passed.
tasks = ["A","C","A","B","D","B"], n = 16A possible sequence is: A -> B -> C -> D -> A -> B. With a cooling interval of 1, you can repeat a task after just one other task.
tasks = ["A","A","A", "B","B","B"], n = 310A possible sequence is: A -> B -> idle -> idle -> A -> B -> idle -> idle -> A -> B. There are only two types of tasks, A and B, which need to be separated by 3 intervals. This leads to idling twice between repetitions of these tasks.
