Smart Home Command Router

A smart home hub receives voice commands. You must route these commands to handlers based on the LONGEST matching prefix registered. If a command starts with 'light.on', it goes to the LightHandler. If it starts with 'light.on.kitchen', it goes to the KitchenHandler. If multiple handlers match, the most specific (longest) one wins. If no prefix matches, print 'UNKNOWN'. Example: Input: 2 light.on LightHandler light.on.kitchen KitchenHandler 2 light.on.bedroom light.on.kitchen.sink Output: LightHandler KitchenHandler
