Q1. Given a 'key', delete the first occurrence of this key in the linked list. Iterative Method: To delete a node from the linked list, we need to do the following steps. 1) Find the previous node of the node to be deleted. 2) Change the next of the previous node. 3) Free memory for the node to be deleted.

- Assume that the node of a linked list is in the usual info-link form with the info of the type int. The following data, as described in parts (a) to (d), is to be insetred into an initially linked list: 72, 43, 8, 12. Suppose that head is a pointer of type nodeType. After the linked list is created, head should point to the first node of the list. Declare additional variables as you need them. Write the C++ code to create the linked list. After the linked list is created, write a code to print the list. What is the output of your code? a. Insert 72 into an empty linked list.b. Insert 43 before 72.c. Insert 8 at the end of the list.d. Insert 12 after 43.Assume that the node of a linked list is in the usual info-link form with the info of the type of int. The following data, as described in parts (a) to (d), is to be inserted into an initially linked list: 72, 43, 8, 12. Suppose that head is a pointer of type nodeType. After the linked list is created, head should point to the first node of the list. Declare additional variables as you need them. Write the C++ code to create the linked list.

Insert 12 after 43in c++ Create a single linked list that contains the data (age) of your friends. Perform basic operations including insertion, deletion, searching and display. The insertion operation should only allow a friend’s data to be inserted in sorted order only.
- IN C LANGUAGE When inserting a node into a linked list, where (in memory) will that node be placed if there is no overflow? A) The location of the AVAIL pointer B) The next contiguous spot of memory from the last node C) The very end of the contiguous memory block D) A randomized memory location1. Write a function to find and return a node, in a single linked list, that has a certain value node * lookup (int v) Then write a function to delete the node after the one returned by the search in question 1 void delete_after(node *p) Then write the main method and give a screenshot of the executionC Programming language Part 1: You need to define a data structure for a doubly linked list and a binary search tree. Also, you need to implement the following functions: Insert Sorted LINKEDLIST insertSorted(LINKEDLIST head, int num): head points to the first node in the sorted linked list; num is a number to be inserted in in correct place in the linked list pointed at “head”. The linked list should be sorted after inserting “num”. This function returns the head of the modified head. BSTREE insert(BSTREE root, int num): root points to a node in a binary search tree; num is a number to be inserted in the tree rooted at “root”. This function returns the root of the modified tree. Find an element LINKEDLIST find(LINKEDLIST head,int num): head points to the first node of a linked list; num is a number to be searched for in the linked list started at “head”. This function returns a pointer to the node containing “num” or NULL if num is not found BSTREE find(BSTREE root,int…
- True/False Select true or false for the statements below. Explain your answers if you like to receive partial credit. 3) Which of the following is true about the insertBeforeCurrent function for a CircularLinked List (CLL) like you did in programming exercise 1?a. If the CLL is empty, you need to create the new node, set it to current, andhave its next pointer refer to itselfb. The worst case performance of the function is O(n)c. If you insert a new element with the same data value as the current node, theperformance improves to O(log n)Think about the following example: A computer program builds and modifies a linked list like follows:Normally, the program would keep tabs on two unique nodes, which are as follows: An explanation of how to use the null reference in the linked list's node in two common circumstancesC++ CODING PROBLEM WHERE I NEED CODE TO CREATE A LINKED LIST (I also put a screen shot of the problem below. Two strings, code1 and code2, are read from input as two states' codes. headObj has the default value of "code". Create a new node firstState with string code1 and insert firstState after headObj. Then, create a second node secondState with string code2 and insert secondState after firstState. Ex: If the input is MA IA, then the output is: code MA IA #include <iostream>using namespace std; class StateNode { public: StateNode(string codeInit = "", StateNode* nextLoc = nullptr); void InsertAfter(StateNode* nodeLoc); StateNode* GetNext(); void PrintNodeData(); private: string codeVal; StateNode* nextNodePtr;}; StateNode::StateNode(string codeInit, StateNode* nextLoc) { this->codeVal = codeInit; this->nextNodePtr = nextLoc;} void StateNode::InsertAfter(StateNode* nodeLoc) { StateNode* tmpNext = nullptr; tmpNext =…
- Think about the following example: A computer program builds and modifies a linked list like follows: Normally, the program would keep tabs on two unique nodes, which are as follows: An explanation of how to use the null reference in the linked list's node in two common circumstancesC Language In a linear linked list, write a function that deletes the element in the middle of the list (free this memory location) (if the list has 100 or 101 elements, it will delete the 50th element). The function will take a list as a parameter and return the updated list.Please code in C language. Please use the starter code to help you solve the deleted node and the reverse list. Here is the starter code: #include <stdio.h> #include <ctype.h> #include <stdlib.h> #include <string.h> #include "linkedlist.h" // print an error message by an error number, and return // the function does not exit from the program // the function does not return a value void error_message(enum ErrorNumber errno) { char *messages[] = { "OK", "Memory allocaton failed.", "Deleting a node is not supported.", "The number is not on the list.", "Sorting is not supported.", "Reversing is not supported.", "Token is too long.", "A number should be specified after character d, a, or p.", "Token is not recognized.", "Invalid error number."}; if (errno < 0 || errno > ERR_END) errno = ERR_END; printf("linkedlist: %s\n", messages[errno]); } node *new_node(int v) { node *p =…
