Computer science questions Which represents a tight upper bound on the runtime of the following code using Big-O notation:sum = 0;for (int i = 0; i < n/2; i += 3) {%3Dfor (int j1; j < n; j *= 3) {%3D}}O(n)O(n)O(logn)O(nlogn)O(1) Which choice below represents code to change these circularly linked nodes:front -> node1 -> node2 -> node3 -> node1Into this:front -> node3 -> node2 -> node1 -> nullIn both cases, front is a variable of type Node referring to the front of the chain of nodes. (Thedefinition of the Node class appears below as a reference.)Here is the code that produces the circularly linked group of nodes shown in the upper diagram:NodecInteger> front = new NodecInteger> (3, null);front = new Node(2, front);front = new Node(1, front);front.next.next.next = front;Here is the Node class:public class NodecE> {protected E element;protected NodecE> next;public Node() {element = null;next = null;public Node(final E theElement, final NodecE> theSuccessor) {element = theElement;next = theSuccessor;front = front.next;front.next.next = front;front = front.next;front.next.next = null;front = front.next.next;front.next = front.next.next;front.next.next = front.next;front.next.next.next = null;front = front.next.next;front.next.next.next = front.next;front.next.next.next = null;front.next - front.next.next;front = front.next.next;front.next.next.next = front.next;front.next = front.next.next;front.next.next.next = null;

typedef struct node_t node_t; struct node_t { }; int32_t value; node_t* next; node_t* insert (node_t* list, int32_t v, int32_t* flag); 3) As you may have noticed from MT1, Howie is lazy. He wants you to write the interface for the following implementation of function copy_to_linked_list. He really appreciates your help! /* copy_to_linked_list int32_t copy_to_linked_list (int32_t a[], int32_t size, node_t** list_p) { int32_t flag, i; for (i = 0; i < size; ++i) { *list_p = insert (*list_p, a[i], &flag); if (-1== flag) return -1; } return 0;
Concatenate Map This function will be given a single parameter known as the Map List. The Map List is a list of maps. Your job is to combine all the maps found in the map list into a single map and return it. There are two rules for addingvalues to the map. You must add key-value pairs to the map in the same order they are found in the Map List. If the key already exists, it cannot be overwritten. In other words, if two or more maps have the same key, the key to be added cannot be overwritten by the subsequent maps. Signature: public static HashMap<String, Integer> concatenateMap(ArrayList<HashMap<String, Integer>> mapList) Example: INPUT: [{b=55, t=20, f=26, n=87, o=93}, {s=95, f=9, n=11, o=71}, {f=89, n=82, o=29}]OUTPUT: {b=55, s=95, t=20, f=26, n=87, o=93} INPUT: [{v=2, f=80, z=43, k=90, n=43}, {d=41, f=98, y=39, n=83}, {d=12, v=61, y=44, n=30}]OUTPUT: {d=41, v=2, f=80, y=39, z=43, k=90, n=43} INPUT: [{p=79, b=10, g=28, h=21, z=62}, {p=5, g=87, h=38}, {p=29,…
@6 The Reference-based Linked Lists: Select all of the following statements that are true. options: As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions. According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node. According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node. In a double-ended singly linked list, the tail reference variable provides access to the entire list. In a circular linked list, the last node references the first node.

Create a node class named LinkedNodes that uses up to 4 dynamic pointers to connect it to the other 8 nodes in the structure (a total of 9). The data in each node will be a unique integer number from 1 through 9. Include in your class definition these functions at a minimum: getVal(), setVal(), getNext(), setNext(), getPrev(), setPrev(), constructor(s) and destructor. Write a simple program to load these nodes into a linked structure. Do not use an array, the pointers will do that for you. You should be able to reach any node from any other node in the structure by traversing a maximum of 2 nodes from the current one. The output from your program should report the traversals between all nodes in the structure, starting with the node whose value is one. (See the example below) Node 1 2 3 4 5 6 7 8 9 -> Traverses to Node 1 Node 2 1->2 2->6->1 3->6->1 3->7->2 4->6->1 4->7->2 4->8->3 5->6->1 5->7->2 5->8->3 6->1->2 6->1->3 7->1->3 8->3 6->1 7->1 8->1 9->1 Node 3 1->3 2->3 7->2 8->2 9->2…

C# Assume you have a LinkedList of Node objects. Both classes have all the normal operations shown below. Your job is to program the DeleteTail method of the LinkedList class. This method locates and deletes the last element of the linked list. You may not change its signature line. Keep your code clean, but no documentation is necessary. A good solution will be between 5 and 10 lines of code, not counting whitespace.
