Idea: Directly copy the data from subsequent nodes and delete the subsequent nodes.Pit: If this node is the tail node of the linked list, then the problem is not solved. The node can be marked as false. Public Static Boolean Deletenode (linkedlistnode N) { ifnullnull) { Returnfalse; } = N.next; = Next.data; = Next.next; return true ;}2.3 Implement an algorithm that deletes a node in the middle of a single-link
