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.
思路:
先考虑特殊情况:(1)链表为空(2)只有一个节点 -- 都直接返回
普通情况:链表不为空,且后续节点也不为空
/** * Definition for singly-linked list. * struct ListNode { * int val; * struct ListNode *next; * }; */ void deleteNode(struct ListNode* node) { if (!node) //链表不为空 return; else if (node->next){ //要删的节点还有后续节点 node->val = node->next->val; node->next = node->next->next; } else //其他情况,如列表不为空且要删除的是最后一个节点 return; }
