class Solution:
    def rotate(self, nums: List[int], k: int) -> None:
        """
        Do not return anything, modify nums in-place instead.
        """
        n=len(nums)
        d=n-(k%n)
    
        # nums[:] is used to make changes to the list while
        # nums[] just changes the reference to the list
        
        nums[:]=nums[d:]+nums[:d]
```
