01 what the model was asked
Create jsonpointer.py with exactly one function:
resolve(doc, pointer: str)
Resolve an RFC 6901 JSON Pointer against doc (nested dicts/lists) and return the referenced value.
Rules:
- The empty pointer "" refers to the whole document.
- A pointer is a sequence of /-prefixed reference tokens: "/a/b" means doc["a"]["b"].
- In a token, the escape ~1 decodes to "/" and ~0 decodes to "~" (decode ~1 before ~0).
- Tokens indexing a list are decimal indices: "/items/0" is the first element.
- Raise KeyError for anything that does not resolve (missing key, bad or out-of-range index, pointer not starting with "/", descending into a scalar).
Use only the Python standard library.
