Single-Threaded CPU Task Scheduling on LeetCode 1834: Understanding Problem Mechanics and Solution Approach
[00:04](   • Understanding Task Scheduling with a Singl...  ) Explains the task scheduling for a single-threaded CPU in LeetCode 1834.
Tasks are presented as a 2D array, with each task having a start time and processing duration.
The CPU processes one task at a time, prioritizing the shortest processing time and breaking ties with the smallest index.
[01:53](   • Understanding Task Scheduling with a Singl...  ) Overview of task scheduling using enqueue and processing times.
Tasks are represented by their enqueue (NQ) and processing times, essential for scheduling on a CPU.
The processing sequence starts with the task having the earliest NQ time, determining idle periods for the CPU.
[03:41](   • Understanding Task Scheduling with a Singl...  ) Task scheduling involves selecting tasks based on shortest processing time.
Tasks are queued at specific times, and the CPU must choose tasks with the shortest processing time.
The selection process involves comparing processing times and updating the task queue accordingly.
[05:25](   • Understanding Task Scheduling with a Singl...  ) Choose the next task based on minimum MQ time and processing duration.
The CPU jumps to the next task's MQ time if idle, selecting the minimum MQ time among available tasks.
When multiple tasks are available, the CPU prioritizes the one with the smallest processing time, using a comparator for tie-breaking.

[07:10](   • Understanding Task Scheduling with a Singl...  ) Task scheduling using a priority queue with dynamic task arrival.
Tasks are sorted by arrival time and processed using a minimum heap to determine the smallest processing time.
The algorithm maintains a pointer for the next task and handles tie-breaking by original indices for scheduling priority.

[09:00](   • Understanding Task Scheduling with a Singl...  ) Task scheduling involves managing arrival and processing times using a priority queue.
While tasks remain and the priority queue isn't empty, advance time to the next task's arrival if needed.
Task processing is simulated by adding task times to the current time and storing indices for CPU scheduling.

[10:55](   • Understanding Task Scheduling with a Singl...  ) Explains task scheduling using NQ time and minimum heaps.
Tasks are sorted by their NQ time and processing time for efficient scheduling.
A minimum heap is used to prioritize tasks based on processing time and their original indices.

[12:47](   • Understanding Task Scheduling with a Singl...  ) Understanding task scheduling using a single-threaded CPU and minimum heap.
Tasks are scheduled based on the earliest available start time and added to a minimum heap when ready.
The algorithm processes tasks in order of lowest processing time, updating current time and tracking task indices.
