        Convert an array of strings to array of numbers

        Oh no!
        Some really funny web dev gave you a sequence of numbers from his API response as an sequence of strings!

        You need to cast the whole array to the correct type.

        Create the function that takes as a parameter a sequence of numbers represented as strings and outputs a sequence of numbers.

        ie:["1", "2", "3"] to [1, 2, 3]

        Note that you can receive floats as well.
