- Question 4 For this question, let's combine ADTS and dictionaries! Let's try to make an ADT that represents a politician. The politician ADT has a constructor make_politician. There are three selectors, get_name, get_party, and get_age. When implementing an ADT, you have the freedom to choose how you want to represent it. Some common data structures used to represent ADTs are lists and dictionaries. The city ADT was implemented using a list. Now, let's use dictionaries to implement our politician ADT. You must use a dictionary for this question, or else you will not pass the tests.def classify(classifier, point): """ return the classification probability for the given point using the given classifier :params: classifier: list of floats, representing the weights for a logistic classifier point: list of values, representing features of a data point. will be same length as list of weights return: float, representing probability that point is from class 1. """ # TODO: implement this! # placeholder; say "50-50" for any point return 0.5Which parenthesis brackets should be used for lists, tuples, dictionaries, and sets?Explain in detail each of these built-in data types.
- Write, test, and debug (if necessary) PHP scripts for the specifications that follow write functions and the code to test them. Parameter: A string containing words that are delimited on the left with spaces and on the right with spaces, commas, periods, or question marks. Return value: The three most common words in the string that have more than three letters Parameter: An array of strings. Return value: A list of the three strings that occur most frequently in the parameter arrayQ1: What are some features and benefits to structured data? Check all that apply. Group of answer choices A method can be passed a structure and the method can then process multiple data items in a structure. 1: Related data items can be under 1 structure definition. 2: Programmers can code structures as they see fit. 3: Structures can be used in arrays to simplify some programming tasks. 4: Multiple variables can be defined using the same structure. Q2: Enumerations are representing constant values and are therefore required to be coded in uppercase characters. True False Q3: Enumerations are stored in memory as ______ . Group of answer choices Integer 1: String 2: Pointer to an internal variable 3: Internal array Q4: Why did the author include enumerations in the same chapter as structured data? Check all that apply. 1: Enumerations are a programmer-defined data type, similar to structured data types being programmer-defined. 2: You can't have structured…Problem You want to implement a custom class that mimics the behavior of a common built-in container type, such as a list or dictionary. However, you're not entirely sure what methods need to be implemented to do it.

- Looking for assistance with this question: Fulcrum def can_balance(items): Each element in items is a physical weight, a positive integer instead of some sort of helium balloon. Your task is to 0ind and return a fulcrum position in this list of weights so that when balanced on that position, the total torque of the items to the left of that position equals the total torque of the items to the right of that position. The item on the fulcrum is assumed to be centered symmetrically on the fulcrum, and does not participate in the torque calculation. In physics, the torque of an item with respect to the fulcrum equals its weight times distance from the fulcrum. If a fulcrum position exists, return that position. Otherwise return -1 to arti0icially indicate that the given items cannot be balanced, at least without rearranging them. items Expected result [6, 1, 10, 5, 4] 2 [10, 3, 3, 2, 1] 1 [7, 3, 4, 2, 9, 7, 4] -1 [42] 0…JavaScript NOTE: Dataset is defined below. Using the data set as a pre-defined variable in your program, write code that uses the dataset to print the FIRST NAMES ONLY of people who have BOTH above average English grades AND below average age from the dataset. The solutions for the textbook examples assume you are able to export in a framework like node.js, which is why in the data set I provide, I simply set the array of objects as a variable. Your code will be in the same file (treat it like any other array variable). You can do the same with the sample files the chapter provides. For example: var ancestry = [ { .. object .. }, ...]// your code here Requirements: Cannot use any array type built-in functions except filter(), map(), and reduce(). var dataSet = [ { "name":"Maura Glass", "age":60, "math":97, "english":63, "yearsOfEducation":4 }, { "name":"James Gates", "age":55, "math":72, "english":96, "yearsOfEducation":10 }, { "name":"Mills Morris", "age":26,…Write JAVA code General Problem Description: It is desired to develop a directory application based on the use of a double-linked list data structure, in which students are kept in order according to their student number. In this context, write the Java codes that will meet the requirements given in detail below. Requirements: Create a class named Student to represent students. In the Student class; student number, name and surname and phone numbers for communication are kept. Student's multiple phones number (multiple mobile phones, home phones, etc.) so phone numbers information will be stored in an “ArrayList”. In the Student class; parameterless, taking all parameters and It is sufficient to have 3 constructor methods, including a copy constructor, get/set methods and toString.
