Linked lists are a fundamental data structure in computer science, frequently used to store collections of elements. Unlike arrays, linked lists provide dynamic memory allocation and efficient insertions and deletions. Understanding and manipulating linked lists is crucial for solving various computational problems. One common task is determining whether two linked lists are identical. Identical linked lists are those that contain the same sequence of elements in the same order. This article delves into the concept of identical linked lists, explaining their significance, the methodology for comparison, and frequently asked questions related to their identification and usage.<\/p>\n
In this problem, we are given two LinkedList and are asked to find if the linked lists are identical or not i.e. we have to find whether the two linked lists have the same arrangement of the values of the nodes in them or not.<\/p>\n
Linked list 1:<\/strong> <\/p>\n Linked List 2:<\/strong><\/p>\n Output:<\/strong> Identical Let’s first understand the problem statement with the help of an example:<\/p>\n If Linked list 1<\/strong> = 3\u21925\u21927 and Linked list 2<\/strong> = 3\u21925\u21927. Since both the linked list have the same arrangement of the values of the nodes, so the above linked list 1 and 2 are Identical<\/strong>.<\/p>\n If Linked list 1<\/strong> = 3\u21925\u21926 and Linked list 2<\/strong> = 3\u21926\u21925.<\/p>\n Since both the linked list have a different arrangement of the values of the nodes, so the above linked list 1 and 2 are Not Identical<\/strong>.<\/p>\n Now, I think from the above examples, it is clear what we are trying to find in this problem. So next we will try to think about how we can approach this problem.<\/p>\n Before jumping to the next section of the blog, try to think about how you can solve this problem?<\/p>\n The basic approach which comes to mind is to traverse both the linked list simultaneously and check if at any iteration:<\/p>\n Else if we reach the end of both the lists at the same time while traversing then only we return true. <\/p>\n Note:<\/strong> If we reach the end in only one list that means their size is different and hence also not identical.<\/p>\n![\"\"](\"https:\/\/prepbytes.com\/blog\/wp-content\/uploads\/2021\/08\/55_1-01.png\")

\nThese two LinkedList are identical.<\/p>\n
\nThe term ‘arrangement of the values of the nodes in a linked list’ which we have referred to in the problem statement means that if our linked list is 5\u21926\u21927\u21928\u21929, then the arrangement of the values of the nodes in the linked list is 5,6,7,8,9.<\/p>\n\n
