How to do this ? If there is a function?

I have a large vector with repeating numbers after some interval. I want to slice it just like how showed in second output.

Thank you 🙂

```julia

julia> a = [1, 1, 1, 1, 2, 2, 2, 2]
12-element Vector{Int64}:
 1
 1
 1
 1
 2
 2
 2
 2

```

```julia
4×2 Matrix{Int64}:
 1 2
 1 2
 1 2
 1 2

```
