Given a sorted linked list, delete all duplicates such that each element appear onlyonce. Example 1: Input: 1->1->2 Output: 1->2 Example 2: Input: 1->1->2->3->3 Output: 1->2->3 很简单的链表问题,可以写成递归和迭代两种形式。具体思路: 第一步,寻找第一个节点值和当前表头所指的节...
(Java) LeetCode 82. Remove Duplicates from Sorted List II —— 删除排序链表中的重复元素 II Given a sorted linked list, delete all nodes that have duplicate numbers, leaving onlydistinctnumbers from the original list. Example 1: Input: 1->2->3->3->4->4->5 Output: 1->2->5 Example ...
ArrayList<Integer>numbersList=newArrayList<>(Arrays.asList(1,1,2,3,3,3,4,5,6,6,6,7,8));LinkedHashSet<Integer>hashSet=newLinkedHashSet<>(items);ArrayList<Integer>listWithoutDuplicates=newArrayList<>(hashSet);System.out.println(listWithoutDuplicates);//[1, 2, 3, 4, 5, 6, 7, 8] Dr...
For example, Given 1->2->3->3->4->4->5, return 1->2->5. Given 1->1->1->2->3, return 2->3. 翻译:将链表中重复的元素全部删除,返回新的头结点。 相比于Remove Duplicates from Sorted List I,这里将重复的元素全部删除。 想要了解Remove Duplicates from Sorted List I,请参考我的这篇博...
从有序链表中删除重复的数字,并且返回删除后的头结点 例如输入链表为1->1->2,返回1->2 这题和leetcode26相似,只是数据结构从数组变成了链表 /** * @author rale * * Given a sorted linked list, delete all duplicates such that each element appear only once. ...
Remove duplicates from a list while keeping the order: >>> from collections import OrderedDict >>> a = ["foo", "Alice", "bar", "foo", "Bob"] >>> list(OrderedDict.fromkeys(a).keys()) ['foo', 'Alice...
Given a sorted linked list, delete all nodes that have duplicate numbers, leaving only distinct numbers from the original list. For example, Given 1->2->3->3->4->4->5, return 1->2->5. Given 1->1->1->2->3, return 2->3. ...
Remove Duplicates from Sorted List 问题:将有序链表中的重复元素删除 分析:由于有序,所以p结点是否重复只需要和它的前一节点比较是否相等就可以了,我们可以定义一个helper新头结点链表 将p结点与新链表的尾结点比较,若不相等则加入新链表中。 代码语言:javascript...
Given a sorted array nums, remove the duplicates in-place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory. ...
If you like to have a function where you can send your lists, and get them back without duplicates, you can create a function and insert the code from the example above. Example defmy_function(x): returnlist(dict.fromkeys(x)) mylist =my_function(["a","b","a","c","c"]) ...
