- Basic mathematical functions operate element-wise on arrays. They are available both as operator overloads and as functions in the NumPy module. import numpy a = numpy.array([1,2,3,4], float) b = numpy.array([5,6,7,8], float) print a + b #[ 6. 8. 10. 12.] print numpy.add(a, b) #[ 6. 8. 10. 12.] print a - b #[-4. -4. -4. -4.] print numpy.subtract(a, b) #[-4. -4. -4. -4.] print a * b #[ 5. 12. 21. 32.] print numpy.multiply(a, b) #[ 5. 12. 21. 32.] print a / b #[ 0.2 0.33333333 0.42857143 0.5 ] print numpy.divide(a, b) #[ 0.2 0.33333333 0.42857143 0.5 ] print a % b #[ 1. 2. 3. 4.] print numpy.mod(a, b) #[ 1. 2. 3. 4.] print a**b #[ 1.00000000e+00 6.40000000e+01 2.18700000e+03 6.55360000e+04] print numpy.power(a, b) #[ 1.00000000e+00 6.40000000e+01 2.18700000e+03 6.55360000e+04] Task You are given two integer arrays, and of dimensions X.Your task is to perform the following operations: Add ( + ) Subtract ( - ) Multiply ( * ) Integer Division ( / ) Mod ( % ) Power ( ** ) NoteThere is a…Javascript toggleCommentSection function The function toggleCommentSection should exist. The function toggleCommentSection should return undefined if not passed a parameter. The function toggleCommentSection should return null if passed a parameter that does not match a post ID. The function toggleCommentSection should select and return the correct section element. The function toggleCommentSection should toggle the 'hide' class on the section The following are requirements of the function toggleCommentSection: element.toggleCommentSection a. Receives a postId as the parameter b. Selects the section element with the data-post-id attribute equal to the postId received as a parameter c. Use code to verify the section exists before attempting to access the classList property d. At this point in your code, the section will not exist. You can create one to test if desired. e. Toggles the class 'hide' on the section element f. Return the section element Here is what I have so far:…javascript Define a function, myIncludes, that accepts two parameters: an array and a searchValue. myIncludes should return true if the searchValue is an element in the array. Otherwise, myIncludes should return false. example myIncludes([10, 20, 30], 20); // => true myIncludes(['apples', 'bananas', 'citrus'], 'pears'); // => false
- Computer Science Part 2: Client Program with ArrayList Create a second client program. This program will contain an ArrayList of StudentGrades objects. The program will perform the following tasks: Create an instance of an ArrayList that will store three StudentGrades objects. Each element in the ArrayList represents student grades for a test (assessment). This means that each StudentGrades object stored by the ArrayList element represents the grades achieved by students for a single test. Prompt the user for the number of students in the class. The prompt text is: Enter the number of students in the course: [Keyboard Input] Add three new StudentGrades objects to the ArrayList. The StudentGrades objects should be populated with random values from 0 to 100. Use the enhanced for loop to print each of the StudentGrades objects to the console. Print a line containing the following text: “LAST ELEMENT BEFORE REMOVE:”. Print the value of the final element in the ArrayList under the heading.…JavaScript //6. addButtonListeners //a.

You may want to define an empty toggleComments function for now. Not all tests //will pass for addButtonListeners until toggleComments exists. I recommend //waiting on the logic inside the toggleComments function until we get there.The purpose of this exercise is to create an Array List data structure that mimics the behavior of the Java Standard Library Version. Task Check List ONLY "for" loops should be used within the data structure class. The names of identifiers MUST match the names listed in the description below. data fields: The fields to declare have private accessibility. size : stores the number of occupied locations in internal array, and is of type int. data : is a reference variable for the internal array and is of type E[ ]. constant: Use to describe defaults. DEFAULT_CAPACITY is a constant that holds a default capacity of ten (10) for the underlying array, is of type int , public accessibility and modified to static. constructors: The overloaded constructors will initialize the data fields size and data. The default constructor calls the second constructor, generating an internal array with the specified DEFAULT_CAPACITY. public ArrayList() The second constructor generates an…
- Computer Science Javascript populateSelectMenu function The function populateSelectMenu should exist. The function populateSelectMenu should return undefined if it does not receive users data. The function populateSelectMenu selects and returns the select menu. The function populateSelectMenu receives the option elements from createSelectOptions and appends them to the select element.MUST BE WRITTEN IN C PROGRAMMING LANGUAGE CANNOT EDIT TEMPLATE IMAGE IN ANY WAY: Write a program to find and display the largest value in an integer array that is divisible by 3. For example, if the array is: 1 15 2 16 3 17 4 18 5 19 The largest number divisible by 3 is 18 On the other hand, if the array does not contain any values that are divisible by 3, the program writesNo value in the array is divisible by 3As you may see in the examples, the input consists of, firstly the size of the array, followed by the array elements. The answer is preloaded with the code to read in the array. Do not change this code. The Moodle checker expects *exactly* the output as shown. For example: Input Result 6 1 2 3 4 5 6 The largest value divisible by 3 is 6 6 1 -2 4 5 -7 8 No value in the array is divisible by 3# 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…
- Transcribed Image Text flipObject(object) Given an object, you will return a new object where the values are now the keys and the keys are now the value. If a value has a type of array, for each element, you will have the element as the key and the value will be the original key. If a value has an object, you will flip those keys and values as well, but keep the key as the same.Write a program in C++ programming language that prompts the user to input any set of elements. The program should display the first and the last element of the array.Create a dynamic array that contains an int array. dynamic array, array inside when the existing array is full and a new element needs to be added will double its size, make all the elements of the old array the same will copy the indexes and add the element to the new array. Use the following functions. Write in C language. 1.append(dynamic array, new element): function sent to itself Adds the element sturct to the end of the array inside DynamicArray. Place If not, it behaves in accordance with the dynamic array definition given above. 2. get(index): The element in the index sent to it by the function takes it from the array it hosts and sends it back. Do not use link lists. Solve the question using array. Use it as a struct DynamicArray.
