When you're in a high-stakes environment like a coding challenge, every millisecond counts. The classic, idiomatic PowerShell style—which relies heavily on the pipeline—can be slower than you might expect. The pipeline introduces overhead from passing objects between cmdlets, making it less efficient for heavy data processing.

Get-Service returns objects representing services on your computer. To see what those objects can do, you run:
