Spoon of Code #2: Remove element from a vector at given index
You have a vector of items
[:a :b :c :d :e :f :g] and you want to remove
the element at index 3 (
; [:a :b :c :e :f :g]
subvec to get two vectors - one with items from first (included), to item
right before provided index
i. Second vector consist of items right after the
element at index
i till the end of the collection.
We then concatenate the two vectors.
vec is there just to make sure we return the same data type the function got.
