Counter via Closure

Closures · medium

Implement `runCounter(start, times)` that creates an internal counter starting at `start`, calls the increment function `times` times, and returns the final counter value. (This exercises building and using a closure internally.)

Hints

Create an inner function that captures and mutates `count`.
Call the inner function `times` times in a loop.
