Implementation of linked list deletion operation:
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:

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 li.
st looks like 1 -> 3 -> 4 ^ | |____|
A linked list is said to contain a cycle if any node is visited more than once while traversing the list. Given a pointer to the head of a linked list, determine if it contains a cycle. If it does, return . Otherwise, return .
Example
refers to the list of nodes
The numbers shown are the node numbers, not their data values. There is no cycle in this list so return .
refers to the list of nodes
There is a cycle where node 3 points back to node 1, so return .
Function Description
Complete the has_cycle function in the editor below.
It has the following parameter:
SinglyLinkedListNode pointer head: a reference to the head of the list
Returns
int: if there is a cycle or if there is not
Note: If the list is empty, will be null.
Input Format
The code stub reads from stdin and passes the appropriate argument to your function. The custom test cases format will not be described for this question due to its complexity. Expand the section for the main function and review the…

- LINKED LIST 1. Let L={x1,x2,…,xn} be a list of n elements. Let us search for a key K in the list L. If the key is presented in the list L then partition the list L into disjoint ordered lists L1 and L2 such that L1={x:xεL such that x≤K} and L2={y:yεL such that y>K}. If the key is not present in the list output is “empty”. Write an algorithm (using linked list) and subsequent C program(Using Pointers) with proper comments for your algorithm to compute lists L1 and L2 for the given list L and key K. Note: Don’t use any inbuilt functions in your program such as sort.Example1: If L={16, 15, 1, 27, 19, 100, 200,3} and key k= 27 then L1={1,3,15,16,19,27} and L2={100,200}.Example 2: If L={16, 15, 1, 27, 19, 100, 200,3} and key k= 127 then empty.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.

- 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_forwardLinked list. Complete the function that takes as a parameter the head of a linked list and prints the linked list in reverse order.
