237. Delete Node in a Linked List（C语言版本）

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.

/** * Definition for singly-linked list. * struct ListNode { *     int val; *     struct ListNode *next; * }; */void deleteNode(struct ListNode* node) {    struct ListNode *temp;    temp = node->next;    node->val = temp->val;    node->next = temp->next;    free(temp);}

解释：这道题虽然让删除一个节点，参数就是那个要删除的节点，题中又指明要删除的节点不是最后一个节点，

     所以可以将该节点的后一个节点的值赋给该节点，删去后面那个节点。
