Kata

To complete this Kata you need to make a function multiplyAll/multiply_all which takes an array of integers as an argument. This function must return another function, which takes a single integer as an argument and returns a new array.

The returned array should consist of each of the elements from the first array multiplied by the integer.

Example:

multiplyAll([1, 2, 3])(2) = [2, 4, 6];

multiply_all([1, 2, 3])(2); // => [2, 4, 6]

multiply_all([1, 2, 3])(2); // => [2, 4, 6]

multiplyAll(Seq(1, 2, 3))(2); // => Seq(2, 4, 6)

(multiply_all [1; 2; 3]) 2 (* [2; 4; 6] *)

You must not mutate the original array.

Here's a nice Youtube video about currying, which might help you if this is new to you.
