Duplicate Set This function will receive a list of elements with duplicate elements. It should add all of the duplicate elements to a set and return the set containing the duplicate elements. A duplicate element is an element found more than one time in the specified list. The order of the set does not matter. Signature: public static HashSet<Object> duplicateSet(ArrayList<Object> list) Example: INPUT: [2, 4, 5, 3, 3, 5] OUTPUT: {5, 3}
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;
Use the following node definition for this problem.struct NodeInt32{int32_t value; NodeInt32* next;} Write a function which searches a non-empty linked list for a target value. Its exact signature should be: NodeInt32* find(NodeInt32* head, int32_t target); The function should return the first node whose value equals target. If the target is not found in the list, then the function should return NULL.
card_t * moveCardBack (card t *head); The moveCardBack function will take the card in front of the pile and place it in the back. In coding terms, you are taking the head of the linked list and moving it to the end. The function has one parameter which is the head of the linked list. After moving the card to the back, the function returns the new head of the linked list.
You have a sorted linked list. Fill in the missing code in the following function. SortedType::DeleteItem(Item Type item) // pointer delete //trailing pointer // traveling pointer void { NodePtr tempPtr; NodePtr predLoc; NodePtr location: bool found false; // Find item to delete: Put your code below //delete item: Put your code below
struct remove_from_front_of_dll { // Function takes no parameters, removes the book at the front of a doubly // linked list, and returns nothing. void operator()(const Book& unused) { //// TO-DO (13) |||| // Write the lines of code to remove the book at the front of "my_dll", // // Remember, attempting to remove an element from an empty data structure is // a logic error. Include code to avoid that. ///// END-TO-DO (13) //// } std::list& my_dll; };
C++ The List class represents a linked list of dynamically allocated elements. The list has only one member variable head which is a pointer that leads to the first element. See the following code for the destructor to List. ~ List () { for (int i = 0; i <size (); i ++) { pop_back (); } } What problems does the destructor have? Select one or more options: 1. There are no parameters for the destructor. 2. The return value from pop_back (if any) is nerver handled. 3. The destructor will create a stack overflow. 4. The destructor will create dangling pointers. 5.The destructor will create memory leaks. 6.The destructor will create undefined behavior (equivalent to zero pointer exception). 7.The condition must be: i <size () - 1 8. There is at least one problem with the destructor, but none of the above.
C++ Code for a QueueThe program should features a Queue class with insert(), remove(), peek(),isFull(), isEmpty(), and size() member functions.The main() program creates a queue of five cells, inserts four items, removes threeitems, and inserts four more. The sixth insertion invokes the wraparound feature. All the items are then removed and displayed. The output looks like this:40 50 60 70 80
Which of the following code segments can be used as a constructor for a node in a linked list. Each node contains a pointer to the next node called next and also has a String called data. O public node () { next = 0; } } public node () { next = "";} } O public node () { next = null; } } O public node () { next = new node(); }
@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.
C++ ProgrammingActivity: Linked List Stack and BracketsExplain the flow of the code not necessarily every line, as long as you explain what the important parts of the code do. The code is already correct, just explain the flow #include "stack.h" #include "linkedlist.h" // SLLStack means Singly Linked List (SLL) Stack class SLLStack : public Stack { LinkedList* list; public: SLLStack() { list = new LinkedList(); } void push(char e) { list->add(e); return; } char pop() { char elem; elem = list->removeTail(); return elem; } char top() { char elem; elem = list->get(size()); return elem; } int size() { return list->size(); } bool isEmpty() { return list->isEmpty(); } };
Having trouble with creating the InsertAtEnd function in the ItemNode.h file below. " // TODO: Define InsertAtEnd() function that inserts a node // to the end of the linked list" Given main(), define an InsertAtEnd() member function in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts ------------------------------------------------------- main.cpp -------------------------------------------------------- #include "ItemNode.h" int main() { ItemNode *headNode; // Create intNode objects ItemNode *currNode; ItemNode *lastNode; string item; int i; int input; // Front of nodes list headNode = new ItemNode(); lastNode = headNode; cin >> input; for (i = 0; i < input; i++) { cin >> item;…
