b. The before->next should point to after.
So that list will be continuous after erasing r from list.
Code should be:
before->next=after;

I am trying to search a name on a list and then remove it by invoking the remove function. However when I search for the name it keeps on saying name not found. What am I doing wrong? (The instruction is in the comments) The remove and drop(delete) coding I have so far is below. void buddyList::remove(buddy * r) { buddy * b4 = head; if (r == head) head = head->next; else { while (b4->next != r) { b4...

The screenshot below states "The singly linked list STL
container std::forward_list has an erase function, which can be
directly used here. But that function erases AFTER the item pointed
to, not the one pointed to like the other containers. A singly
linked list cannot look backwards, only forward. You need to
convert the zero-based offset from the top to an iterator by
advancing _groceries_sl_list.before_begin() offsetFromTop times.
The STL has a function called std::next() that does that, or you
can write...

Program 2: Linked List Class For this problem, let us take the linked list we wrote in a functional manner in a previous assignment and convert it into a Linked List class. For extra practice with pointers we'll expand its functionality and make it a doubly linked list with the ability to traverse in both directions. Since the list is doubly linked, each node will have the following structure: struct...

Design and implement your own linked list class to hold a sorted list of integers in ascending order. The class should have member function for inserting an item in the list, deleting an item from the list, and searching the list for an item. Note: the search function should return the position of the item in the list (first item at position 0) and -1 if not found. In addition, it should member functions to display the list, check if...

Complete P16.1 and P16.4 (Class Name: NewMethodDemo) Once complete, upload all .java files. For primary test class: Remember your header with name, date, and assignment. Also include class names that will be tested. Psuedocode (level 0 or mixture of level 0 and algorithm [do not number steps]) is required if main() contains more than simple statements (for example, your program includes constructs for decisions (if/else), loops, and methods. For Secondary class(es): Include a JavaDoc comment that describes the purpose of...

Introduction In this lab, you are supposed to implement a graph class with the data structure implemented before like linked list and queue. graph The class graph contains three member variables: linkedList *adjacentVertices; //an array of linked list. For a vertice i, adjacentVertices[i] stores the linked list that contains all other vertices connected to vertice i. int numVertices; //The number of vertices in the graph. int maxNumVertices; //The maximum number of vertices the graph can hold. Following public methods are...
