Suggested Problem Name: Device Name System

Suggested Function Name: deviceNamesSystem

Create unique device names to be used in a residential loT (Internet of Things) system. If a device name already exists in the system, an integer number is added at the end of the name to make it unique. The integer added starts with 1 and is incremented by 1 for each new request of an existing device name. Given a list of device name requests, process all requests and return an array of the corresponding unique device names.

Example

n = 6

devicenames = ['switch', 'tv, 'switch, tv, 'switch, tv] •

devicenames[0] = "switch" is unique, uniqueDevicename[0) - "switch •

devicenames[1] = " is unique, unique Devicename/Oj-"tv •

devicenames/2) = devicenames(OJ. Add 1 at the end the previous unique username "switch", uniqueDevicename/2) -"switch 1" •

devicenames[3) = devicenames[1]. Add 1 at the end the previous unique username "v", uniqueDevicename/3) - tv1" •
