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) { if(node == NULL) { return; } node->val = node->next->val; node->next = node->next->next; }
