Leetcode：237. Delete Node in a Linked List(JAVA)

【问题描述】

Write a function to delete a node (except the tail) in a singly linked list, given only access to that node.

Supposed the linked list is 1 -> 2 -> 3 -> 4 and you are given the third node with value 3, the linked list should become 1 -> 2 -> 4 after calling your function.

public void deleteNode(ListNode node){if (node != null) {node.val = node.next.val;node.next = node.next.next;}else {return;}}
