Implement `multiplyAll(factor, nums)` that builds a multiplier by calling a `makeMultiplier(factor)` function which returns a function, then maps it over `nums`.

Sample tests

Input: multiplyAll(3, [1,2,3])

Output: [3,6,9]

Input: multiplyAll(0, [5])

Output: [0]

+ 1 hidden test run on Submit.

Hints

Common pitfalls

Returning the factory itself instead of calling it.

Approach & explanation (try first)

makeMultiplier returns a closure bound to factor, used directly as the map callback.
