    Linked Lists

    linked list is much like any other list implementation in computer science but for the fact that the nodes carry references (also called pointers) to their next (and sometimes previous) nodes as well as the value attribute (also called the cargo or payload). Linked lists are one of the most commonly used data structures as this property allows for efficient removal and insertion of elements at any point along the list, unlike arrays which require reorganizing the entire structure and the possible need to allocate more space to it altogether as array elements must be stored continuously in memory. In addition, they are tools for implementing other common abstract data types like associative arrays, queues, stacks and S-structures, only adding to their popularity. 

    The first element in a linked list is known as its head while the last is its tail, though some use 'tail' to refer to every node after the head. The common linked list operations are as follows:

    • create a linked list (add a head node)
    • add a node:



    • delete a node:



    • change the order of two nodes
    • count the number of items in the list

    One must be quite careful with pointers when removing and inserting nodes to make sure the order is not perturbed.

    Sorted and Unsorted Lists in C++ Data Structures

    I need some ideas for dealing with list data that would have more permanence and be stored and retrieved as needed instead of the program beginning with an empty list, data being added and manipulated and the program ending by freeing the data. Use code fragments to illustrate your response.

    Contiguous, Linked, Indexed Strategy

    Consider a file system on a disk that has both logical and physical block sizes of 512 bytes. Assume that the information about each file is already in memory. For each of the three allocation strategies (contiguous, linked, and indexed), answer these questions: 1. How is the logical-to-physical address mapping accomplished i

    Data Structure Problem : stack class implementation with push/pop

    File Reverser Write a program that opens a text file and reads its contents into a stack of characters. The program should then pop the characters from the stack and save them in a second text file. The order of the characters saved in the second file should be the reverse of their order in the first file. Requirement: stac

    Erase all occurrences of a target in linked list

    Extend the function eraseValue() to erase all occurrences of "target" in the linked list. template < typename T > void eraseAll (node * & front, const T& target); This is the implementation of eraseValue() that must be modified. { node< T > *curr = front, *prev = NULL; bool foundItem = false; while (curr != NU

    Matrices: Two-Dimensional Cartesian Structures

    One of the problems of storing data in a matrix (a two-dimensional Cartesian structure) is that if not all of the elements are used, there might be quite a waste of space. In order to handle this, we can use a construct called a "sparse matrix", where only the active elements appear. Each such element is accompanied by its two i

    You are preparing for a meeting of designers and programmers. The goal of the meeting is to review existing portfolio web pages to generate design ideas on presenting images in a gallery.

    First, discuss in general terms what you think the role of good design is. Next, identify three characteristics of an effective gallery website. Then find an example of a portfolio website containing thumbnail imagery. Critically evaluate and discuss what makes the site effective (if you have chosen a poorly designed site, discu
