Given a sorted linked list, delete all duplicates such that each element appear only once.
For example,
Given 1->1->2, return 1->2.
Given 1->1->2->3->3, return 1->2->3.
思路:链表是有序的。每次判断当前元素与新链表尾部元素是否相同,若相同,则将其跳过;否则,将其加入新链表尾部。
1 class Solution { 2 public: 3 ListNode *deleteDuplicates( ListNode *head ) { 4 if( !head ) { return head; } 5 ListNode *node = head; 6 while( node->next ) { 7 if( node->val == node->next->val ) { 8 node->next = node->next->next; 9 } else { 10 node = node->next; 11 } 12 } 13 return head; 14 } 15 };
Remove Duplicates from Sorted List
