# Create Custom Transformer Create a custom transformer, just as we did in the lecture video entitled "Custom Transformers", that performs two computations: 1. Adds an attribute to the end of the numerical data (i.e. new last column) that is equal to $\frac{x_1^3}{x_5}$ for each observation. In other words, for each instance, you will cube the $x_1$ column and then divide by the $x_5$ column. 2. Drops the entire $x_4$ feature column if the passed function argument `drop_x4` is `True` and doesn't drop the column if `drop_x4` is `False`. (See further instructions below.) You must name your custom transformer class `Assignment4Transformer`. Your class should include an input parameter called `drop_x4` with a default value of `True` that deletes the $x_4$ feature column when its value is `True`, but preserves the $x_4$ feature column when you pass a value of `False`. This transformer will be used in a pipeline. In that pipeline, an imputer will be run *before* this transformer. Keep…

Two strings, color1 and color2, are read from input as two desks' colors. headObj has the default value of "color". Create a new node firstDesk with string color1 and insert firstDesk after headObj. Then, create a second node secondDesk with string color2 and insert secondDesk after firstDesk. Ex: If the input is gold maroon, then the output is: color gold maroon

CHALLENGE ACTIVITY 5.10.2: Simon says Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings starting from index 0. For each match, add one paint to userScore. Upon a mismatch, exit the loop using a break statement Assume simon Pattern and userPattern are always the same length. Ex The following patterns yield a userScore of 4: simonPattern: RRGBRYYBGY userPattern: RRGBBRYBGY Learn how our autograde works 13 14 simonPattern- scnr.next(); userPattern - scnr.nextO: 15 16 17 for (i=0; i<10; i++) { 18 if O[ simornPattern: 19 20 21 if ( 22 23 24 userPattern: 25 26 returns System.out.println("userScore: userScore); 매매

Exercise 15.1In the above program make the necessary changes so that a new struct, date, is defined for the expiration date of theproduct. Thus, an expiration date, day, month, and year, will be associated with each node. Use the following expirationdates for each item:Rolls 08/10/2003Jam 09/12/2003Tea 01/01/2010 #include <iostream>#include <cstddef>#include <string>using namespace std;struct Node{string item;int count;Node *link;};typedef Node* NodePtr;void head_insert(NodePtr& head, string an_item, int a_number);void show_list(NodePtr& head);int main(){NodePtr head = NULL;head_insert(head, "Tea", 2);head_insert(head, "Jam", 3);head_insert(head, "Rolls", 10);show_list(head);return 0;} void head_insert(NodePtr& head, string an_item, int a_number){NodePtr temp_ptr;temp_ptr = new Node;temp_ptr-> item = an_item;temp_ptr-> count = a_number;temp_ptr->link = head;head = temp_ptr;}void show_list(NodePtr& head){NodePtr here = head;while (here !=…
True/False Select true or false for the statements below. Explain your answers if you like to receive partial credit. 3) Which of the following is true about the insertBeforeCurrent function for a CircularLinked List (CLL) like you did in programming exercise 1?a. If the CLL is empty, you need to create the new node, set it to current, andhave its next pointer refer to itselfb. The worst case performance of the function is O(n)c. If you insert a new element with the same data value as the current node, theperformance improves to O(log n)
