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

Given a positive integer n, return the punishment number of n.
The punishment number of n is defined as the sum of the squares of all integers i such that:

1 <= i <= n
The decimal representation of i * i can be partitioned into contiguous substrings such that the sum of the integer values of these substrings equals i.

 
Please complete the following python code precisely:
```python
class Solution:
    def punishmentNumber(self, n: int) -> int:
```
