#The challenge

write a function

    func(small_array, size_bigarray, divisor, index_where_small_array_begins, size_smallarray)

The function does the following:

Imagine a `big array` with `size bigarray`. (you don't have the array explicity)

It is filled with `zero`s. Except from `index_where_small_array_begins` the values of the `big_array` are identically with `small_array`.

`small_array` contains only positive numbers. (not zero)

So `small_array` is a part of `big_array`. (you can assume it fits, that means `index_where_small_array_begins` + `size_smallarray` <= `size_bigarray`)

Now split the `big_array` in `mini_arrays` of size `divisor`. (If `divisor` is not a divisor of `size_bigarray`, the last array is smaller)

(Example `size_bigarray` = 10, `divisor` = 3, then you have four arrays of size: 3, 3, 3, 1)

For each of the `mini_array` you add the values together, call it `sum_of_the_miniarray`.

Print out an array with `sum_of_the_miniarray` for all `miniarrays` for which the `sum_of_the_miniarray` is nonzero. (You can conclude that from `index_where_small_array_begins` and `size_smallarray`)

Example:
Given:

    small_array = [1,2,3]
    index_where_small_array_begins = 4
    size_bigarray = 8
    divisor = 3

then big_array would be:

    big_array = [0,0,0,0,1,2,3,0]

the mini arrays would be

    [0,0,0] [0,1,2] [3,0]

the sums would be

    0 3 3

But you only output `[3,3]` because the first one is zero.

-----------------------------------------------------------

#The rules

You are not allowed to construct the big array explicitly!

You are not allowed to construct the mini arrays explicitly!

That means you have to get the computation directly from the small_array!

Fewest characters wins!

Good luck!
