题目一 题目 O(1)时间复杂度删除给定链表节点. 题解 用待删除节点后一个节点的值覆盖待删除节点值,更新链接关系. 注意链表只有一个节点:删除尾结点:删除头节点的处理. 代码 class ListNode { int val; ListNode next = null; ListNode(int val) { this.val = val; } } public class Main { public static void main(String[] args) { //test case
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 ->
2.3 Implement an algorithm to delete a node in the middle of a singly linked list, given only access to that node.EXAMPLEInput: the node c from the linked list a->b->c->d->eResult: nothing is returned, but the new linked list looks like a- >
