- Create a list – l1 with element 1,2,3,4,5. Convert this list into an array name ar. What is the dimension of this array – one dimension, 2 dimension or multidimension What is the datatype of elements of array. Print the second element of an array. Create a nested list – l2 with three lists. Elements of each lists are – [1,2,3];[4,5,6];[7,8,9] Convert this list into an array ar2. What is the dimension of this array. Observe the parenthesis. Print 8 from this array. Without using list, create an array ar3, which has the even number from 2 -10. Use the np.arange(start, end, skip). Run the following code and observe the output.Design a class that acquires the JSON string from question #1 and converts it to a class data member dictionary. Your class produces data sorted by key or value but not both. Provide searching by key capabilities to your class. Provide string functionality to convert the dictionary back into a JSON string. question #1: import requestsfrom bs4 import BeautifulSoupimport json class WebScraping: def __init__(self,url): self.url = url self.response = requests.get(self.url) self.soup = BeautifulSoup(self.response.text, 'html.parser') def extract_data(self): data = [] lines = self.response.text.splitlines()[57:] # Skip the first 57 lines for line in lines: if line.startswith('#'): # Skip comment lines continue values = line.split() row = { 'year': int(values[0]), 'month': int(values[1]), 'decimal_date': float(values[2]),…1. Use a below-given starter code. Use StackInterface.(h), and ArrayStack.(h,cpp). You will write your own StackDriver.cpp application file. IT'S IN C++Also...If the class that you create is Star, remember that you will declare your stack as follows:ArrayStack<Star> myStarStack;and you will push, pop, and peek Star objects.2. Create your own class definition. I should have at least one attribute, a constructor, and set and get methods for each attribute in your class.NOTE: If your class is offensive your lab will be rejected and you will receive a score of zero. I'm sorry I have to say this but there is a history of this happening and it is not appropriate.3. Write a driver program that exercises the Stack class from the downloaded starter code. Create multiple instances of your own class and demonstrate the stack operations: push, pop, and peek. ( you write your own class that you will put on the stack and you will write a driver that pushes, peeks, and pops your class items…
- i) Create a Node class which will hold two fields i.e an integer element and a reference to the next Node. ii) Create a Linked list Abstract Data Type (ADT)named MyList.The elements in the list are Nodes consisting of an integer type key (all keys are unique) and a reference to the next node. [You are not allowed to use any global variable other than head] If you are using PYTHON, make sure your code has the methods invoked through test statements and proper printing statements according to the tasks. You may create a separate Tester class for this or test the methods within the MyList class. Write a code in pythonWhich of the following data structures store values in contiguous memory?

A Each data element connects to the next element in the map. B It's a data structure that stores data pairs: keys and their associated values. C Each data element can connect to multiple related elements in a map. D It's a data structure that keeps its data sorted.Create a program (or set of programs) which accomplish the following for each complex data type (list,tuple,set,frozenset, dictionary): create the item with at least 4 elements Append an element Remove an element Insert an element in the middle somewhere Append another array of the same data type Append another array of a different data type (for example, if you have a dictionary, append a set or tuples And do the following: Output the results after each step. Report and explain any errors (if a line of code generates an error, comment it out along with a comment on what the error was and your reasons for that error) Create a range of negative numbers Create a range of positive even numbers Insert a range into each data type that would allow it Please explain each error you ran into
