Can you solve this real interview question? Remove Duplicates from Sorted List II - Given the head of a sorted linked list, delete all nodes that have duplicate numbers, leaving only distinct numbers from the original list. Return the linked list sorted
Remove Duplicates from Sorted List Given a sorted linked list, delete all duplicates such that each element appear onlyonce. For example, Given1->1->2, return1->2. Given1->1->2->3->3, return1->2->3. 这个就跟数组中重复元素合并差不多,只需要考虑当前节点与下一个节点的关系。 只需要...
