# 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…

def is_left_handed(pips):
Even though this has no effect on fairness, pips from one to six are not painted on dice just any which way, but so that pips on the opposite faces always add up to seven. (This convention makes it easier to tell when someone tries to use crooked dice with certain undesirable pip values replaced with values that are more desirable for the cheater.) In each of the 23 = 8 corners of the cube, exactly one value from each pair of forbidden opposites 1-6, 2-5 and 3-4 meets two values chosen from the other two pairs of opposites. You can twist and turn any corner of the die to face you, and yet two opposite sides never spread into simultaneous view.
This discipline still allows for two distinct ways to paint the pips. If the numbers in the corner shared by the faces 1, 2, and 3 read out clockwise as 1-2-3, that die is left-handed, whereas if they read out as 1-3-2, that die is right-handed. Analogous to a pair of shoes made separately for the left and…

Arrays
Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print:
7 9 11 10 10 11 9 7
Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1. (Notes)Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades[4]). See "How to Use zyBooks".Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message.

Nearest polygonal number def nearest_polygonal_number(n, s):
Any positive integer s > 2 defines an infinite sequence of s-gonal numbers whose i:th element is given by the formula ((s-2)i2 - (s-4)i)/2, as explained on the Wikipedia page "Polygonal Number". In this formula, positions start from 1, not 0, and we use the letter i to denote the position since we will be using the letter n for something else. For example, the sequence of "octagonal numbers" that springs forth from s = 8 starts with 1, 8, 21, 40, 65, 96, 133, 176...
Given the number of sides s and an arbitrary integer n, this function should return the s-gonal integer closest to n. If n falls exactly halfway between two s-gonal numbers, return the smaller one.
As you can see from the last row of the previous table, this function must be efficient even for gargantuan values of n. The simplest way to make this function efficient is to harness the power of repeated halving to pull your wagon with a clever application of…

def eliminate_neighbours(items):
Given the sequence of integer items that are guaranteed to be some permutation of positive integers from 1 to n where n is the length of the list, find the smallest number among those that still remain in the list, and remove from the list both that number and whichever of its current immediate neighbours is larger. The function should repeat this basic operation until the largest number in the original list gets eliminated. Return the number of removal operations that were needed to achieve this goal.For example, given the list [5, 2, 1, 4, 6, 3], the operation would remove element 1 and its current larger neighbour 4, resulting in the list [5, 2, 6, 3]. Applied again, that operation would remove 2 and its current larger neighbour 6, thus reaching the goal in two steps.

Geometric Progression Printer
As you might recall, a Geometric Progression (or GP) is a sequence of elements in which the next number in the sequence is obtained by multiplying the previous number by the
common ratio.
The next number in the sequence is obtained by using this formula:
a_n=a_1*r(n-1)
While the sum of all numbers in the sequence is obtained using any of these formulae:
If r= 1, sum=a*n
Ifr != 1 and r> 1, sum = a[(rª-1)/(r - 1)]
Ifr != 1 and r < 1, sum = a[(1-r)/(1-r)]
where a_n = next number in the sequence, a_1 = first number in the sequence, r = common ratio, n = number of terms
Your task is to write a Python program that
1: Accepts the necessary inputs from the user, i.e., start value (a_1), common ratio (r), and number of generate to generate (n).
2. Generates the Geometric Progression (GP) sequence starting from a_1 to n.

def eliminate_neighbours (items):
Given the sequence of integer items that are guaranteed to be some permutation of positive
integers from 1 to n where n is the length of the list, find the smallest number among those that still

needed to achieve this goal.
For example, given the list [5, 2, 1, 4, 6, 31, the operation would remove element 1 and its
current larger neighbour 4, resulting in the list [5, 2, 6, 3]. Applied again, that operation

Background: When searching for an item in a list, each item that we examine (compare) is considered to be interrogated.
If we search for John, the following names are interrogated: Harry, Larry, John (in that order). If two names tie for the middle position, choose the first of the two names for the middle.If we search this same list for John using the Sequential search we would interrogate all the names from Alice through John. We would start with Alice, move to Bob, move to Carol and so forth until we reached John.
Directions: Use the original list of names (Alice - Oliver) to answers questions 1-8.
Using a sequential search, what names are interrogated to find Carol?
Using a sequential search, what names are interrogated to determine that Sam is not in the list?
Using a binary search, what names are interrogated to find Carol?
Using a binary search, what names are interrogated to determine that Sam is not in the list?
Will a binary search or sequential search find Alice…

(This convention makes it easier to tell when someone tries to use crooked dice with certain undesirable pip values replaced with values that are more desirable for the cheater.) In each of the 23 = 8 corners of the cube, exactly one value from each pair of forbidden opposites 1-6, 2-5 and 3-4 meets two values chosen from the other two pairs of opposites. You can twist and turn any corner of the die to face you, and yet two opposite sides never spread into simultaneous view. This discipline still allows for two distinct ways to paint the pips. If the numbers in the corner shared by the faces 1, 2, and 3 read out clockwise as 1-2-3, that die is left-handed, whereas if they read out as 1-3-2, that die is right-handed. Analogous to a pair of shoes made separately for the left and…arrow_forward

- Arrays Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print: 7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1. (Notes)Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades[4]). See "How to Use zyBooks".Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. #include <iostream>using namespace std; int main() {const int NUM_VALS = 4;int courseGrades[NUM_VALS];int i; for (i = 0; i < NUM_VALS; ++i) {cin >> courseGrades[i];} /* Your…arrow_forwardNearest polygonal number def nearest_polygonal_number(n, s): Any positive integer s > 2 defines an infinite sequence of s-gonal numbers whose i:th element is given by the formula ((s-2)i2 - (s-4)i)/2, as explained on the Wikipedia page "Polygonal Number". In this formula, positions start from 1, not 0, and we use the letter i to denote the position since we will be using the letter n for something else. For example, the sequence of "octagonal numbers" that springs forth from s = 8 starts with 1, 8, 21, 40, 65, 96, 133, 176... Given the number of sides s and an arbitrary integer n, this function should return the s-gonal integer closest to n. If n falls exactly halfway between two s-gonal numbers, return the smaller one. As you can see from the last row of the previous table, this function must be efficient even for gargantuan values of n. The simplest way to make this function efficient is to harness the power of repeated halving to pull your wagon with a clever application of…arrow_forwardPull down your neighbours def eliminate_neighbours(items): Given the sequence of integer items that are guaranteed to be some permutation of positive integers from 1 to n where n is the length of the list, find the smallest number among those that still remain in the list, and remove from the list both that number and whichever of its current immediate neighbours is larger. The function should repeat this basic operation until the largest number in the original list gets eliminated. Return the number of removal operations that were needed to achieve this goal.For example, given the list [5, 2, 1, 4, 6, 3], the operation would remove element 1 and its current larger neighbour 4, resulting in the list [5, 2, 6, 3]. Applied again, that operation would remove 2 and its current larger neighbour 6, thus reaching the goal in two steps. items Expected result [1, 6, 4, 2, 5, 3] 1 [8, 3, 4, 1, 7, 2, 6, 5] 3 [8, 5, 3, 1, 7, 2, 6, 4] 4 [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] 5 range(1,…arrow_forward
