In this article, we will be solving LeetCode’s swapping in node a linked list in JavaScript. Solving LeetCode’s ‘Swapping Nodes in a Linked List’ - Return the head of the linked list after Swapping Node the values of the kth nodes from the beginning and the kth node from the end (the list is 1-indexed).

In this article, we will be solving LeetCode’s Swapping Nodes in a Linked List in JavaScript.

Here is an article I wrote on Linked Lists and goes through a LeetCode problem.

Recap, a linked list is a linear collection of nodes where each node points to the next node. Each node has a value property and a next property which references the next node in the list.

This is what makes linked lists a linear data structure. There is a sequence and an order to the list. To get to the end of the list, we must start at the first node (head) and go through all of the nodes in order. The final node (tail) will point to null, indicating that is the end of the list.

You are given the head of a linked list, and an integer k.

Return the head of the linked list after **swapping** the values of the kth node from the beginning and the kth node from the end (**the list is 1-indexed**).

Swapping Nodes

```
Input: head = [1,2,3,4,5], k = 2
Output: [1,4,3,2,5]
```

Linked List in Data Structure. In computer science, we refer to the format of storing data on storage devices as a data structure. An array is the collection of data stored in contiguous memory locations.
