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...
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. 题意:链表升序排列,删掉重复链表中的重复节点 代码: /*** Definition for singly-linked list. * public class ListNode...
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. * For example, * Given 1->1->2,...

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"]) ...
Let’s look at a simple example of using distinct() to remove duplicate elements from alist. package com.journaldev.java; import java.util.ArrayList; import java.util.List; import java.util.stream.Collectors; public class JavaStreamDistinct { ...
