Understanding deletion at a given distance

Deleting a node at a distance X is similar to inserting a node at a given distance. Just like inserting at a distance X We can solve this problem without keeping track of the previous node while traversing. However, we must consider a few special cases, so let’s examine them.

1. The list is empty

When the list is empty, meaning it contains no elements, any attempt to delete a node is unnecessary because there are no nodes in the list. Since there is nothing to remove, the list remains unchanged. We can return the existing head, as the list is empty, and no node needs to be deleted.
