Please solve the programming task below using a self-contained code snippet in a markdown code block.

You are given two integers height and width representing a garden of size height x width. You are also given:

an array tree where tree = [treer, treec] is the position of the tree in the garden,
an array squirrel where squirrel = [squirrelr, squirrelc] is the position of the squirrel in the garden,
and an array nuts where nuts[i] = [nutir, nutic] is the position of the ith nut in the garden.

The squirrel can only take at most one nut at one time and can move in four directions: up, down, left, and right, to the adjacent cell.
Return the minimal distance for the squirrel to collect all the nuts and put them under the tree one by one.
The distance is the number of moves.
 
Please complete the following python code precisely:
```python
class Solution:
    def minDistance(self, height: int, width: int, tree: List[int], squirrel: List[int], nuts: List[List[int]]) -> int:
```
