In this exercise you'll be completing an array-based and a link-based stack collection type discussed in this chapter. Both have similar implementations, but a link-based stack uses nodes and an array-based stack can resize the array if necessary. In the LinkedStack class of the linkedstack.py file, complete the following: Complete the implementation of the constructor method. __init__, sets the initial state of self, which includes the contents of sourceCollection, if it's present. Complete the implementation of the accessor methods. __iter__, supports iteration over a view of self and visits items from bottom to top of stack. peek(), returns the item at the top of the stack. Precondition: the stack is not empty. Raises: KeyError if the stack is empty. Complete the implementation of the mutator methods. clear(), makes self become empty. push(), adds item to the top of the stack. pop(), removes and returns the item at the top of the stack. Precondition: the stack is not…
1. According to the following LinkedList, write pseudo code for the question belowHow do you insert a node with the data, "Brandon" between the node of "Chu" and the node of "Bethany"? 2.Assume that there is a linked list that connected several names.How do you set up a "while" loop to print the whole list? 3.What is the advantage of using a LinkedList over an ArrayList?
The firstLastList.cpp application, which illustrates a double-ended list, can be found in Implementing a Double-Ended List. Don't mistake the double-ended list for the doubly linked list, incidentally.
A singly linked list can perform insertion and deletion of nodes from both ends in constant time. True or False?
Create a collection. Along with GETMAX, MAXSTACK supports the ADT procedures of PUSH, POP, and EMPTYSTACK and behaves like a standard linked stack. The GETMAX function logs the largest element in the stack. Can you construct the array so that GETMAX only requires O(1) time complexity?
How to get insert method to accept two values? Right now it accepts one, and ignores the other. class Node: """ Represents a node in a linked list """ def __init__(self, data): self.data = data self.next = None class LinkedList: """ A linked list implementation of the List ADT """ def __init__(self): self._head = None def add(self, val): """ Adds a node containing val to the linked list """ self._head = self.rec_add(self._head, val) def rec_add(self, a_node, val): """ Adds a node containing val to the linked list """ if a_node is None: return Node(val) else: a_node.next = self.rec_add(a_node.next, val) return a_node def insert(self, val, pos): """ Adds a node containing val to the linked list """ self._head = self.insert_add(self._head, val, pos) def insert_add(self, a_node, val, pos): """…

Q.4 What does the following function do for a given Linked List? (2)void fun1(struct node* head){if(head == NULL)return;fun1(head->next);printf("%d ", head->data);}
Please implement this function: void swap(int pos1, int pos2) {}. There's an answer from the previous teacher but he added '' node** hRef " in the function (see below) please correct without the href. For LinkedList, to maintain integrity of data in the structure, you are not to swap directly the element, nor remove a node. Instead, you are to only change the nodes' next pointers. PLEASE CORRECT THIS ONE void swap(node** hRef, int pos1, int pos2) { if (pos1 == pos2) return; node *prevNode1 = NULL; node* currNode1 = *hRef; while (currNode1 && currNode1->index != pos1) { prevNode1 = currNode1; currNode1 = currNode1->next; } node *prevNode2 = NULL; node *currNode2 = *hRef; while (currNode2 && currNode2->index != pos2) { prevNode2 = currNode2; currNode2 = currNode2->next; } if (currNode1 == NULL || currNode2 == NULL) return; if (prevNode1 != NULL) prevNode1->next =…
implement this method: numOccurrencesRec(LNode node, int n, int key) – This method takes as parameters a reference to the head of a linked list, a position specified by n, and a key. It returns the number of occurrences of the key in the linked list beginning at the n-th node. If n = 0, it means you should search in the entire linked list. If n = 1, then you should skip the first node in the list.
What does the following function do for a given Linked List with first node as head? void fun1(struct node* head) { if(head == NULL) return; fun1(head->next); printf("%d ", head->data); } a) Prints all nodes of linked listsb) Prints all nodes of linked list in reverse orderc) Prints alternate nodes of Linked Listd) Prints alternate nodes in reverse order
For this question you are going to provide code fragments thatimplement two methods. You do not need to provide anything other than those twomethods. Imagine using a doubly linked list to implement the stack ADT for values of a generic type. Skeleton code is provided below. Implement the push and pop methods. Instead of using the methods of the List ADT, manipulate the nodes directly. Make sure to handle any major error conditions by throwing a new RuntimeException. This doubly linked list uses sentinel nodes and you can assume that beginMarker and endMarker have already been initialized properly. class LinkedListStack { private static class Node { public Node(E d, Node p, Node n) { data = d; prev = p; next = n; } Node prev; Node next; E data; } Node beginMarker; Node endMarker; public void push(E x) { /* put the code for this in the file that you will upload */ } public E pop() { /* put the code for this…
