Consider the following structure of a node for a linked list. struct Node { int key; Node *next; }; What will be the output of the following pseudo-code? Assume, head is a pointer to the first node of the following linked list. 5->2->8->2->9->2->11-> NULL Node *pres head; 0; while(pres!= NULL && Count key : int count 2) { count = count + 1; } pres = pres->next; } cout key « endl; 11 Error 2.
Assume a linked list contains following integers: 7, 2, 9, 5, 8, 3, 15 and the pointer head is pointing to the first node of the list. What will be the value of variable a after the following statements are executed: Node<int> *curNode=head; Node<int> *aNode; int s; while(curNode!=NULL){ { aNode=curNode; curNode=curNode->getNext(); } s=aNode->getItem(); A. 15 B. 3 C. 7 D. 2
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 location

Given an IntNode struct and the operating functions for a linked list, complete the following functions to extend the functionality of the linked list(this is not graded).
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 circumstances
True or False For each statement below, indicate whether you think it is True or False. If you like, you can provide a description of your answer for partial credit in case you are incorrect. Use the standard linked list below to answer True/False statements 9-12: 8 7 null 4 10 The “head” pointer of this list is pointing to Node 4 If we called “insert(5)”, the new node’s “next” pointer will point to Node 8 If we called “delete(10)”, Node 7’s “next” pointer will point to Node 8 If we called “search(20)”, the “head” pointer will be at Node 4 after the search function ends
Assuming the node class has already been created, start your code from the method: def swapReplaceMidOdd(head, element): #write your code here
