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. 思路:定义两个指针,pre和cur,如果cur和pre相等,则cur移动;如果不相等,同时移动。 1 2 3 4 5 6 7 8 9 10 11 1...
ArrayList<Integer>numbersList=newArrayList<>(Arrays.asList(1,1,2,3,3,3,4,5,6,6,6,7,8));List<Integer>listWithoutDuplicates=numbersList.stream().distinct().collect(Collectors.toList());System.out.println(listWithoutDuplicates);//[1, 2, 3, 4, 5, 6, 7, 8] This method does not mod...
然后让第一个指针的next指向第二个指针,两个指针同时往后挪,进行下面的操作。 需要注意,当list的结尾几个node是重复的时候,例如1->2->3->3,那么ptr2会指向null,需要特殊处理,令ptr1.next = null,这样list尾部就不会丢。 其他情况就不用特殊处理结尾了,因为结尾没有重复值,只须遍历就够了,不用特殊处理尾部...
