Solve the following python programming problem given the following code:

    " compare 2 dict/list, return a list containing
    json-pointer indicating what's different, and what's diff exactly.

    - list length diff: (jp, length of src, length of dst)
    - dict key diff: (jp, None, None)
    - when src is dict or list, and dst is not: (jp, type(src), type(dst))
    - other: (jp, src, dst)
