Linked List:
A linear data structure where each element denotes a separate object is known as linked list.
- Each element of a list contains two items, the data and a pointer to next node.
- The last node would point to null.
- The “head” denotes point of entry into a linked list.
- If list is empty then the head is a null pointer.
- The structure of linked list is given below:

Find the existence of an intersection between two (singly) linked lists. Send back the node that intersects. Keep in mind that reference, not value, is used to define the intersection. This means that they are intersecting if the kth node of the first linked list is the exact same node (by reference) as the jth node of the second linked list.
Look for a point where two (singly) linked lists intersect. Return the intersection node. Remember that the intersection is defined by reference rather than value. If the kth node of the first linked list is the exact same node (by reference) as the jth node of the second linked list, then they are intersecting.
Reverse a singly linked list by changing the pointers of the nodes. The datarepresented by the list should continue to remain in the same nodes of the originallist.For example, given a singly linked list START, as shown in Figure P6.9(a), the listneeds to be reversed, as shown in Figure P6.9(b), by manipulating the links alone.

- Suppose there are two singly linked lists both of which intersect at some point and become a single linked list. The head or start pointers of both the lists are known, but the intersecting node is unknown. Also, the number of nodes in each of the list before they intersect are unknown and both the list may have it different. List1 may have n nodes before it reaches intersection point and List2 might have m nodes before it reaches intersection point where m and n may be m = n, m > n or m < n. Give an algorithm for finding the merging point. Hints: A brute force approach would be to compare every pointer in one list with every pointer in another list. But in this case the complexity would be O(mn)arrow_forwardDetermine if an intersection exists between two (singly) linked lists. Return the intersection node. Keep in mind that the intersection is defined by reference rather than value. This indicates that they intersect if the kth node of the first linked list is the same as the jth node of the second linked list (by reference).arrow_forwardConsider a list of data components L[0:5] = 23, 14, 98, 45, 67, and 53. Let's look for the K = 53 key. Naturally, the search moves down the list, comparing key K with each element until it discovers it as the final element in the list. When looking for the key K = 110, the search moves forward but eventually drops off the list, making it a failed search. Write the algorithmic steps for both sorted and unordered linear searches, along with the times involved.arrow_forward
- In which of the following Linked list last node is pointed to first node and first node is pointed to last node? a. Circular Double Linked List. b. Circular Single Linked List. c. Depends on the problem. d. Circular Linked List.arrow_forwardIf a node is in a linked list with N nodes, how many nodes will be traversed during a search for the node? Explain the best- and worst-case search scenarios. Explain why a singly-linked list defines a RemoveAfter() function, while a doubly-linked list defines a Remove() function. Could a RemoveAfter() function also be defined for a doubly-linked list? Explain why or why not. Could a Remove() function also be defined for a singly-linked list? Explain why or why not.arrow_forwardConsider a (singly) linked list. Describe an algorithm to remove every second elementfrom the list.(HINT: The algorithm is similar to the one that is used when we delete a single node. Here,we need to skip an element after every deletion, and then if we have not reached the end ofthe list repeat this procedure until the list is exhausted.).arrow_forward
