How do you find the union of two linked lists?
Method 1 (Simple) Go through list1 and find all its elements in list2, if the element is present in list2, then add the element to the result. Union(list1, list2): Initializes the result list to NULL. Loop through list1 and add all its elements to the result.

Is it possible to produce the union of two linked lists?
More complex variants add additional links, allowing more efficient insertion or removal of nodes at arbitrary positions. The union of two linked lists can be found by merging the lists in an orderly manner. The intersection of the two lists can be found by taking only common elements when merging the two lists.
How do you find the intersection of two linked lists in C?
This solution requires modifications to the basic data structure of the linked list. Have a visited flag with each node. Loop through the first linked list and keep checking the visited nodes. Now loop through the second linked list. If you see a visited node again, then there is an intersection point, return the intersection node.
How do you link two linked lists?
The new list must be made by splicing the nodes of the first two lists. For example, if the first linked list a is 5->10->15 and the other linked list b is 2->3->20, SortedMerge() should return a pointer to the parent node of the merged list 2->3 ->5->10->15->20.
How do you concatenate a linked list to show it through an example?
Algorithm for concatenation
- If the first linked list is empty, it returns head2.
- If the second linked list is empty, it returns head1.
- Stores the address of the starting node of the first link. list into a pointer variable, say p.
- Move the p to.
- Stores the address of the first node of the second linked.
How do I combine two unordered linked lists?
Combine two unordered linked lists to get an ordered list
- Concatenate the two lists by traversing the first list until we reach its end node, and then point the next end node to the parent node of the second list. Store this concatenated list in the first list.
- Sort the combined linked list above.
How to find Union and intersection of two linked lists?
Write a C program to find the union and intersection of two linked lists. Algorithm to find the intersection and union of two singly linked lists. Given two singly linked lists, we have to create two linked lists containing the union and intersection of both linked lists respectively. For example:
How to get Union and intersection in Excel?
Implementation: The steps to follow to obtain union and intersection lists are detailed below. 1) Sort both linked lists using merge sort. This step takes time O (mLogm). 2) Linearly scan both ordered lists to get the union and intersection. This step takes O(m + n) time.
How is a linked list a data structure?
It is a data structure consisting of a collection of nodes that together represent a sequence. In its most basic form, each node contains data and a reference (in other words, a link) to the next node in the sequence. This structure allows efficient insertion or removal of elements from any position in the sequence during iteration.
