用JavaScript 实现链表操作 - 08 Remove Duplicates TL;DR 为一个已排序的链表去重,考虑到很长的链表,需要尾调用优化。系列目录见前言和目录。 需求 实现一个removeDuplicates()函数,给定一个升序排列过的链表,去除链表中重复的元素,并返回修改后的链表。理想情况下链表只应该被遍历一次。 var list = 1 -> 2 ->...
3) Remove duplicates using a Set TheSetobject lets you store unique values of any type, whether primitive values or object references. This method requires us to convert our data array to a set. Duplicates will be automatically removed. Then we convert the set back to an array. letmyData=[...
First of all you should be able to write the code inline (ie.const userIds = [...new Set(maybeDupeIds)];) and it’s still legible, most JavaScript engineers will understand what’s happening there (we’re creating a new de-duped Array frommaybeDupeIds). The second reason is that th...
There are multiple ways to remove duplicates from an array. The simplest approach (in my opinion) is to use theSetobject which lets you storeunique valuesof any type. In other words,Setwill automatically remove duplicates for us. constnames=['John','Paul','George','Ringo','John'];letuniq...

Given a sorted array nums, remove the duplicates in-place such that each element appears only once and returns 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. ...
First, we are creating a newSetby passing an array. BecauseSetonly allows unique values, all duplicates will be removed. Now the duplicates are gone, we're going to convert it back to an array by using the spread operator... constarray=['🐑',1,2,'🐑','🐑',3];// Step 1cons...
