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

An array A is larger than some array B if for the first index i where A[i] != B[i], A[i] > B[i].
For example, consider 0-indexing:

[1,3,2,4] > [1,2,2,4], since at index 1, 3 > 2.
[1,4,4,4] < [2,1,1,1], since at index 0, 1 < 2.

A subarray is a contiguous subsequence of the array.
Given an integer array nums of distinct integers, return the largest subarray of nums of length k.
 
Please complete the following python code precisely:
```python
class Solution:
    def largestSubarray(self, nums: List[int], k: int) -> List[int]:
```
