 A room, in the context of this challenge, is a multidimensional array where the elements on the "outside" are `1`, to represent the walls, and all the other elements are `0` (empty space inside the room)

Here's a 1D room with size 5:

```
[1,0,0,0,1]
```

And here's a 2D room with size 6x4:
```
[[1,1,1,1],
 [1,0,0,1],
 [1,0,0,1],
 [1,0,0,1],
 [1,0,0,1],
 [1,1,1,1]]
```

It's 6x4 and not 4x6 because the list has length 6 at depth 1, and length 4 at depth 2.

Or a 4x4x4 room (imagine each 4x4 sub-array as a 2D slice of the 3D room):

```
[[[1,1,1,1],
 [1,1,1,1],
 [1,1,1,1],
 [1,1,1,1]],
 [[1,1,1,1],
 [1,0,0,1],
 [1,0,0,1],
 [1,1,1,1]],
 [[1,1,1,1],
 [1,0,0,1],
 [1,0,0,1],
 [1,1,1,1]],
 [[1,1,1,1],
 [1,1,1,1],
 [1,1,1,1],
 [1,1,1,1]]]
```

A room can be recursively defined by starting with `0` and replacing each `0` with `[1,0,0,...,0,1]` and each 1 with `[1,1,...,1,1]`, each to the appropriate length and depth.

Your challenge is to take a list of integers and output a room with those dimensions. Dimensions will always be \$ >1 \$. A dimension value of 2 means no space inside, so if there's a 2 the whole thing will be `1`s.

You may use any two consistent values instead of `0` and `1` to represent space and wall.

Output may be as a flattened string, e.g. [3,4] => `111110011111`.

You may take the coordinate list reversed (inside out).

[4,4,4] => [ [ [1,1,1,1], [1,1,1,1], [1,1,1,1], [1,1,1,1] ], [ [1,1,1,1], [1,0,0,1], [1,0,0,1], [1,1,1,1] ], [ [1,1,1,1], [1,0,0,1], [1,0,0,1], [1,1,1,1] ], [ [1,1,1,1], [1,1,1,1], [1,1,1,1], [1,1,1,1] ] ]
[5,6] => [ [1,1,1,1,1,1], [1,0,0,0,0,1], [1,0,0,0,0,1], [1,0,0,0,0,1], [1,1,1,1,1,1] ]
[3,19] => [ [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1], [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1], [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1] ]
[12] => [1,0,0,0,0,0,0,0,0,0,0,1]
```
