Merge Two Linked List Data Structure | DSA Tutorials

Merge Two Linked Lists – Today, we are going to learn how to merge a linked list into another linked list. like we have two linked lists, as you see in Figure 1. The first linked list has four nodes.

The second linked list has three nodes.

So we want to merge the second list into the first list. First, we need to find the reference to the last node of the first linked list.

Then we store the second linked list’s first node’s reference into the linked part of the last node of the first linked list.

So now the second linked list is merged into the first linked list.
