Program Plan Intro
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:

Determine 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).
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)
What are the requirements for determining if a linked list T is empty if T is one of the following: (i) a simple singly linked list, (ii) a headed singly linked list, (iii) a simple circularly linked list, or (iv) a headed circularly linked list?

- Merge2AscListsRecur that combines the nodes in X-list and Y-list into Z-list such that, after calling the function, Z-list is a sorted list (in non-decreasing order) containing all the nodes initially contained in X-list and Y-list – X-list and Y-list should both be empty after the call. The function should: ► Have only three parameters (each a pointer-to-Node) and no return value (be a void function). ► Not use any global variables or static local variables. ► Not use any looping constructs (for, while, do-while, ...). ► Be directly (not indirectly) recursive. ► Not create any new nodes, destroy any existing nodes or copy/replace the data item of any node. ► Not make temporary copies of the data involved using any other storage structures (arrays, stacks, queues, etc.). ► Use (if ever needed) no more than a small number of pointers to hold certain link addresses. ○ Not make temporary copies of the…arrow_forwardGiven pointers to the head nodes of linked lists that merge together at some point, find the node where the two lists merge. The merge point is where both lists point to the same node, i.e. they reference the same memory location. It is guaranteed that the two head nodes will be different, and neither will be NULL. If the lists share a common node, return that node's value. Note: After the merge point, both lists will share the same node pointers.

- 09.Given a linked list of N nodes such that it may contain a loop. A loop here means that the last node of the link list is connected to the node at position X(1-based index). If the link list does not have any loop, X=0. Remove the loop from the linked list, if it is present, i.e. unlink the last node which is forming the loop. Example 1: Input: N = 3 value[] = {1,3,4} X = 2 Output: 1 Explanation: The link list looks like 1 -> 3 -> 4 ^ | |____|arrow_forwardwrite a program to find second maximum node in circular link list. First you design structure of circular linked list then perform these functionality.arrow_forwardQuestion Given a singly linked list, you need to do two tasks. Swap the first node with the last node. Then count the number of nodes and if the number of nodes is an odd number then delete the first node, otherwise delete the last node of the linked list. For example, if the given linked list is 1->2->3->4->5 then the linked list should be modified to 2->3->4->1. Because 1 and 5 will be swapped and 5 will be deleted as the number of nodes in this linked list is 5 which is an odd number, that means the first node which contains 5 has been deleted. If the input linked list is NULL, then it should remain NULL. If the input linked list has 1 node, then this node should be deleted and a new head should be returned. Sample 1: Input: NULL output: NULL. Sample 2: Input: 1 output: NULL Sample 3: Input: 1->2 output: 2 Sample 4: Input: 1->2->3 output: 2->1 Sample 5: Input: 1->2->3->4 _output: 4->2->3 Sample 6: Input: 1->2->3->4->5->6 output: 6->2->3->4->5.
