/**

* RandomScheduling is an algorithm that assigns tasks in a random order.
|
||||
* It doesn't consider priority, deadlines, or burst times, making it
|
||||
* inefficient but useful in scenarios where fairness or unpredictability
|
||||
* is required (e.g., load balancing in distributed systems).
|
||||
*
|
||||
* Use Case: Distributed systems where randomness helps avoid task starvation.
