Разбить массив чисел на два массива

Разбить массив чисел на два массива?

Split an array of numbers into two arrays?

[Marcin Romaszewicz]

It's very simple to do that:

I'm not sure if that is a good idea 😅

This is why three-index slices were added in Go 1.2.

Unfortunately a[i:j:k] acts exactly like a[i:j] if i+k >= cap(a)
and appending to subslice can mutate the underlying slice.

[Dan Kortschak]

What do you mean by i+k >= cap(a)? k+(any non-negative number) may not
be greater than cap(a). The key to safely appending when you are unsure
of the backing array's state is to append to the slice length and
capped to the same size.
