Rbtree has a range interface of d. Its memory layout is similar 
to a linked list, where the data is not contiguous. So, you have 
to copy the elements manually. But it is always a nice practice 
to use library functions, doing it for you.

```d
     import std.container.rbtree;
     import std.array;

     auto rbt = redBlackTree(3, 1, 4, 2, 5);
     auto arr = rbt[].array;

     writeln(arr);
```
