Implement the remove(u) method, that removes the node u from a MeldableHeap. This method should run in O(log n) expected time. Use c++
Step by step
Solved in 4 steps with 3 images
- Implement a recursive function void deleteMax() on the IntList class (provided). The function will delete from the IntList the IntNode containing the largest value. If there are multiple nodes containing this largest value, only delete the 1st one. Be careful not to cause any memory leaks or dangling pointers. You may NOT use any kind of loop (must use recursion). You may NOT use global or static variables. You may NOT use any standard library functions. Ex: list: 5->7->1->16->4->16->3 list.deleteMax(); list: 5->7->1->4->16->3 IntList.h #ifndef __INTLIST_H__#define __INTLIST_H__ #include <ostream> using namespace std; struct IntNode {int value;IntNode *next;IntNode(int value) : value(value), next(nullptr) {}}; class IntList { private:IntNode *head; public: /* Initializes an empty list.*/IntList() : head(nullptr) {} /* Inserts a data value to the front of the list.*/void push_front(int val) {if (!head) {head = new IntNode(val);} else {IntNode…how to implement this function by giving another example like this function or any similar : int* returnNeighbors(int v);// returns the indices of the neighbors of the vertex v as an int arrayPROGRAM IN C++ Our BoardArray will store 5 entries maximum.

While the algorithm for this problem might seem trivial, its implementation is not. In general, it is not advisable to modify a list while you are iterating on it, as in the following pseudo-code: for element in myList: if <condition>: <remove element(s) from myList> # recipe for disasterCAN THE SOLUTION BE SUBMITTED WITH TEXT AND NOT A PDF IMAGE PLEASE! This assignment requires you to write a non-verbose input-driven java program for maintaining a binary search tree (BST) of integer elements (negative, zero or positive). The speciality of your BST will be that itwill record the frequency of occurrence for each integer element in it. Actions provisioned on the BST. When your program is running, a user should be able to select one of the following actions to be performed on the BST. 1. Insert an element into the BST2. Search for an element in the BST3. Find the maximum element from the BST4. Find the minimum element from the BST5. Print the elements in the BST in preorder6. Print the elements in the BST in postorder7. Print the elements in the BST in inorder8. Delete an element Anything else to exit the program. The user will provide their choice of action on the BST, by entering one of the numbers between 1 to 8 thatcorrespond to their choice. For example, if the…

- Ask the user to enter a series of integers, and store these numbers into a linked list. The user can enter as many numbers as she like, so your program must keep asking for more until she enters -100 to signify she wants to stop. Please note that your program must store the number into a *linked list*, and not an array, because in theory, the user can enter unlimited number of integers, and all array has a fixed size. * Implement a C function to perform merge sort. This function takes the linked list above as the input, and sort it using the Merge Sort algorithm. You do have a choice here: You can either perform the merge sort directly on the linked list (more fun), or copy the numbers from the linked lists into an array first, and then sort the array (more familiar).I need some help with this problem. my instructions are "Write a recursive void method to display a single-ended singly linked list backwards. " i am using custom code for links and a linked list that comes from my textbook. the textbook is "Data Structures and Algorithms in Java Second Edition" by Robert Lafore in my code i made a method called recursiveReverse() which takes two arguments a integer count and an integer sizeOfList is supposed to use a for loop to get the method to where it needs to go on the list using a current and previous link. the current is where the method is at currently and the previous is where the current was before the list iterated. i am having trouble finding a way to get the method to end when the code finally gets to where it needs to be. the code before the first recursion should reach the end of the list and then count should be incremented in the recursion argument. the code presented is still not completely finished but please let me know if i am…Write a method replace to be included in the class KWLinkedList (for doubly linked list) that accepts two parameters, searchItem and repItem of type E. The method searches for searchItem in the doubly linked list, if found then replace it with repItem and return true. If the searchItem is not found in the doubly linked list, then insert repItem at the end of the linked list and return false. Assume that the list is not empty. You can use ListIterator and its methods to search the searchItem in the list and replace it with repItem if found. Do not call any method of class KWLinkedList to add a new node at the end of the list. Method Heading: public boolean replace(E searchItem, E repItem) Example: searchItem: 15 repItem: 17 List (before method call): 9 10 15 20 4 5 6 List (after method call) : 9 10 17 20 4 5 6
