Background

The worker pool pattern is essential for controlling concurrency. Instead of spawning unlimited goroutines, you create a fixed number of workers that process jobs from a queue.

Your Task

Implement a worker pool that:

1. Creates a configurable number of workers
2. Processes jobs from a shared channel
3. Each job is a number that should be squared
4. Collects results and prints them

Key Concepts

• Worker pool pattern: Fixed number of workers processing from a queue
• Buffered channels: Using buffer to decouple producers and consumers
• WaitGroup: Waiting for multiple goroutines to complete
• Channel closing: Signaling no more values will be sent
