372. Delete Node in the Middle of Singly Linked List

It is marked as “EASY” but…

KEY: It doesn’t give you the head node. So you have to “link” previous node to the next node somehow.

SOLUTION: copy node.next to node and handle the links and values appropriately.


public class Solution {
* @param node: the node in the list should be deleted
* @return: nothing
public void deleteNode(ListNode node) {
// write your code here
if(node == null || node.next == null)

ListNode next = node.next;
node.val = next.val;
node.next = node.next.next;
