Please read our. printLinkedList has the following parameter(s): The first line of input contains , the number of elements in the linked list. Linked list is the second most-used data structure after array. If the head pointer is null (indicating the list is empty), there is nothing to print. A linked list is a sequence of data structures, which are connected together via links. Please Improve this article if you find anything incorrect by clicking on the "Improve Article" button below. it will hold the reference of the next node. Node data structure of a linked list has two parts – a) data and b) link. The first node is called the head. Since array elements are contiguous locations, there is locality of reference which is not there in case of linked lists. code. We use cookies to ensure you have the best browsing experience on our website. The task is to print the elements of the second linked list according to the position pointed out by the data in the nodes of the first linked list. Given a pointer to the head node of a linked list, print each node's element, one per line. The outer loop points to the elements of the first list and the inner loop point to the elements of the second list respectively. Examples: Input: l1 = 1->2->5 l2 = 1->8->7->6->2->9->10 Output : 1->8->2 Elements in l1 are 1, 2 and 5. This challenge is part of a MyCodeSchool tutorial track and is accompanied by a video lesson. The next lines contain one element each, the values for each node. So, the printLinkedList function should print 16 and 13 each on a new line. The task is to print the elements of the second linked list according to the position pointed out by the data in the nodes of the first linked list. close, link We use cookies to ensure you have the best browsing experience on our website. Example Linked list: 29->34->43->56->88 Input: 1 2 4 Output: 34 43 88. I hope you have understood how to perform basic operations on singly and doubly linked list in C. If you wish to learn Linked List in Java, here’s a complete guide. You must also be familiar with dynamic memory allocation and structures. Representation: A linked list is represented by a pointer to the first node of the linked list. See your article appearing on the GeeksforGeeks main page and help other Geeks. Here the data part is simply an integer but it can be arbitrarily complex. The next variable is the link that will point to the next node i.e. brightness_4 In the first iteration of outer loop, the pointer to the head of the first linked list points to its root node. Get hold of all the important DSA concepts with the DSA Self Paced Course at a student-friendly price and become industry ready. Linked lists are the best and simplest example of a dynamic data structure that uses pointers for its implementation. Note: Do not read any input from stdin/console. For example, if the first linked list is 1->2->5 then you have to print the 1st, 2nd and 5th elements of the second linked list. If you come across any questions, feel free to ask all your questions in the comments section of “Linked List in C” and our team will be glad to answer. Please write to us at contribute@geeksforgeeks.org to report any issue with the above content. Writing code in comment? Unlike array linked list generally don’t have index so we have to traverse the whole linked list and print the data when we reached a particular. If the head pointer is null (indicating the list is empty), there is nothing to print. Below is the implementation of the above approach: edit If the linked list is … Please use ide.geeksforgeeks.org, generate link and share the link here. A linked list a data structure for storing a collection of data elements. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.geeksforgeeks.org or mail your article to contribute@geeksforgeeks.org. We traverse the second linked list until we reach the position pointed out by the node’s data in the first linked list. Each link contains a connection to another link. Complete the printLinkedList function in the editor below.
