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

You are given an integer array nums, which contains distinct elements and an integer k.
A subset is called a k-Free subset if it contains no two elements with an absolute difference equal to k. Notice that the empty set is a k-Free subset.
Return the number of k-Free subsets of nums.
A subset of an array is a selection of elements (possibly none) of the array.
 
Please complete the following python code precisely:
```python
class Solution:
    def countTheNumOfKFreeSubsets(self, nums: List[int], k: int) -> int:
```
