PART 4: How To Remove Redundant Rules ? 13. Sometimes it is desirable to remove the rules that are subset of larger rules. To do so, use the below code to filter the redundant rules. subsetRules <- which(colSums(is.subset(rules, rules)) > 1) # get subset rules in vector length(subsetRules) 3913 rules <- rules[-subsetRules] # remove subset rules.

- Please,help me by providing C++ programing solution. Do not use the LinkedList class or any classes that offers list functions. Implement a LinkList in C++. Pease,implement with an ItemType class and a NodeType structThe program should read a data file,and the data file has two lines of data as follow:100, 110, 120, 130, 140, 150, 160100, 130, 160The program will first add all of the numbers from the file,then display all of them,then delete.For this assignment, you need to implement link-based List and derivative ADTs in Java. To complete this, you will need the following: A LinkNode structure or class which will have two attributes - a data attribute and a pointer attribute to the next node. The data attribute of the LinkNode should be the Money class of Lab 1. A Singly Linked List class which will be composed of three attributes - a count attribute, a LinkedNode pointer/reference attribute pointing to the start of the list and a LinkedNode pointer/reference attribute pointing to the end of the list. Since this is a class, make sure all these attributes are private. The attribute names for the Node and Linked List are the words in bold in #1 and #2. For the Linked List, implement the most common linked-list behaviors as explained in class - getters/setters/constructors/destructors for the attributes of the class, (a) create new list, (b) add data, (c) delete data, (d) find data, (e) count of data items in the…Q4 Suppose, alist is a 2-dimensional list that is defined as follows. alist = [ [1], [2,3], [5,6,7] ] Which is the best option to access the last element of the last element of this list (i.e., 7)? Question 4 options: alist[ len(alist) - 1 ][len(alist[len(alist) - 1]) - 1] alist[ len(alist) - 1 ][len(alist[len(alist) - 1])] alist[3][3] alist[ len(alist) - 1 ][1]
- in C++ kth ElementExtend the class linkedListType by adding the following operations:a. Write a function that returns the info of the kth element of the linked list. If no such element exists, terminate the program.b. Write a function that deletes the kth element of the linked list. If no such element exists, terminate the program. Provide the definitions of these functions in the class linkedListType. please, do not copy from any other sources, give me a fresh new code. Thank youThere’s a somewhat imperfect analogy between a linked list and a railroad train, where individual cars represent links. Imagine how you would carry out various linked list operations, such as those implemented by the member functions insertFirst(), removeFirst(), and remove(int key) from the LinkList class in this hour. Also implement an insertAfter() function. You’ll need some sidings and switches. You can use a model train set if you have one. Otherwise, try drawing tracks on a piece of paper and using business cards for train cars.Please help me in this question: 15/ Direct mapping is set associative mapping with a set size of _____ . a. 1 b. 2 c. N / 2 d. N Thank you!
- Subject : Data Stuctures A. Draw BST from the following values: 2, 9, 4, 15, 20, 7, 12, 1, 18 B. Write the Preorder and post order traversal of the BST drawn in part A)- the constructor needs to initialize tailPtr to nullptr - insert(): modify it to update prev pointers as well as next pointers. - remove(): modify to update prev pointers as well as next pointers. Add a new public member function to the LinkedList class named reverse() which reverses the items in the list. swap each node’s prev/next pointers, and finally swap headPtr/tailPtr. Demonstrate your function works by creating a sample list of a few entries in main(), printing out the contents of the list, reversing the list, and then printing out the contents of the list again to show that the list has been reversed. Note: your function must actually reverse the items in the doubly-linked list, not just print them out in reverse order! we won't use the copy constructor in this assignment, and as such you aren't required to update the copy constructor to work with a doubly-linked list. @file LinkedList.cpp */ #include "LinkedList.h" // Header file#include <cassert>#include…In this chapter, the class to implement the nodes of a linked list is defined as a struct.

Write the functions as described in the class for the following purposes.1. Write a c++ function to create a dynamic sorted (in ascending order according to the age)doubly linked list, where the data component of each node is an instance of the structStudent.2. Write a function to insert the instances in the linked list. You also need to write a function to find the spot for insertion of the nodes.3. Write a function to remove the node from the linked list.4. Write a function to count the elements of the linked list.5. Write a function to determine check whether an element belongs to the linked list.6. Write a function to print the linked list (from head node) on the console.7. Write a function to print the linked list (from tail node) on the console. Implement the above functions as follows.Initially, the list must have five nodes that are the instances of the struct whose member…1. Suppose you have already developed an SLL ADT. You have to search a specificelement of the linked list. If you find the element in the list then you have to swapits previous node with its next node. Otherwise, simply print the message “Datanot found”. Now write a function in your SLL ADT with this functionality.
