<s>[INST] I have a list of 30 numbers which each have a corresponding set of 3 integers that make up its "position" and a single integer that makes up its "value". An example of what the data might look like is:
```
[
  {"position": [1, 1, 1], "value": 1},
  {"position": [1, 1, 2], "value": 2},
  {"position": [1, 1, 3], "value": 3},
  ...
]
```
I want to write some code to generate a 3D numpy array that represents this list. The 3D numpy array should have dimensions equal to the maximum value of each position plus one, and each element in the array should be equal to the "value" of the corresponding item in the list. If an item is missing from the list, the corresponding element in the array should be equal to zero.

Here is the code I've written so far:
```
import numpy as np[/INST]
