The following function doubles every element of the list, but does so using mutation. Notice how this causes the second test of each pair to fail, because the original variable is changed. Modify the function so that double_elements no longer mutates the list, but still produces a double list. Please use Python.

- About initial programming in python: Create a function that receives as parameters a list of 4 elements [name,[phone(s)], email, instagram] and a phone number:• If the phone number is in the list, it must be removed.• If not, no updates will be made. Note: phone(s) is within another list. Your function should only return a Boolean value, indicating whether the change was made or not. To find out if the function did the phone deletion correctly, you should check the contents of the list with the contact details you used to test your function after executing it. In the image is the model of parameters, in this case the function must exclude from the list of 4 elements the indicated number '44322456' and return "True".In python, create a function wherein you transfer elements from a list into different lists. If a certain element has been encountered, continue the listing in a new list. Continue doing so until this certain element has been encountered two times. Disregard the succeeding elements after the second certain element. Once you have your 2 lists, return them both as a tuple. Example: element_stop = ‘a’ original_list = [‘b’, ‘c’, ‘d’, ‘d’, ‘f’, ‘a’, ‘e’, ‘t’, ‘d’, ‘g’, ‘f’, ‘t’, ‘a’, ‘b’, ‘e’] The output should be: ([‘b’, ‘c’, ‘d’, ‘d’, ‘f’], [‘e’, ‘t’, ‘d’, ‘g’, ‘f’, ‘t’])in python. Please include docstring. Write a recursive function named list_max that takes as its parameter a list of numbers and returns the maximum value in the list. You can assume the list contains at least one element. If multiple elements of the list are tied for the maximum, you would still return that value. You cannot call the built-in max() function. You may use default arguments and/or helper functions. Your recursive function must not: use any loops use any variables declared outside of the function use any mutable default arguments (see the Code Style Requirements)
- The function interleave_lists in python takes two parameters, L1 and L2, both lists. Notice that the lists may have different lengths. The function accumulates a new list by appending alternating items from L1 and L2 until one list has been exhausted. The remaining items from the other list are then appended to the end of the new list, and the new list is returned. For example, if L1 = ["hop", "skip", "jump", "rest"] and L2 = ["up", "down"], then the function would return the list: ["hop", "up", "skip", "down", "jump", "rest"]. HINT: Python has a built-in function min() which is helpful here. Initialize accumulator variable newlist to be an empty list Set min_length = min(len(L1), len(L2)), the smaller of the two list lengths Use a for loop to iterate k over range(min_length) to do the first part of this function's work. On each iteration, append to newlist the item from index k in L1, and then append the item from index k in L2 (two appends on each iteration). AFTER the loop…Notice that all of the data in the inner lists are represented as strings. You are to write the function convert_data, which should make modifications to the inner lists according to the following rules: If and only if a string represents a whole number (ex: '3' or '3.0'), convert the string to an int. If and only if a string represents a number that is not a whole number (ex: '3.14'), convert the string to a float. Otherwise, leave the string as a str.HINT: The provided helper function is_number may be used (attached image). QUESTION: Complete the docstring below.def convert_data(data: List[list]) -> None: """Convert each string in data to an int if and only if it represents a whole number, and a float if and only if it represents a number that is not a whole number. >>> d = [['abc', '123', '45.6', 'car', 'Bike']] >>> convert_data(d) >>> d [['abc', 123, 45.6, 'car', 'Bike']] >>> d = [['ab2'], ['-123'], ['BIKES', '3.2'],…In python. Please include docstring, and follow the code style requirements below. Thanks. Write a recursive function named list_max that takes as its parameter a list of numbers and returns the maximum value in the list. You can assume the list contains at least one element. If multiple elements of the list are tied for the maximum, you would still return that value. You cannot call the built-in max() function. You may use default arguments and/or helper functions. Your recursive function must not: use any loops use any variables declared outside of the function use any mutable default arguments (see the Code Style Requirements)
- Write a function with below starting function: public static void printFirstAnd Last(ArrayList list) The approach should accomplish the following: Print "no elements" if the list is empty. Print the single element in the list if there is only one. Print the first entry in a list with more than one element, followed by a space, and then the last element.Although working with sets is quick and easy in Python, sometimes we might want to find the union between two lists. Create a function called unite_lists, which uses a loop to go through both lists and return common elements. Do not use the built-in set functionThe List method reverse() reverses the elements in the list. In the reverse.py file, complete the following: Define a function named reverse() that reverses the elements in its list argument. Do not use the List method .reverse(). Try to make the function as efficient as possible. State its computational complexity using big-O notation in the docString/headerDoc. To test your program run the main() method in the reverse.py file. Your program's output should look like the following: [3, 2, 1, 0] [2, 1, 0]
- Use the Design Recipe to define a function remove_value that consumes a list and a value and returns a list containing all the elements except the ones that match the value. Do not use any built-in functions and do not modify the original list. design recipe just means to define the function. this is for PythonWhich of the following statements regarding linked lists and arrays is correct? Group of answer choices: a. A dynamically resizable array makes insertions at the beginning of an array very efficient. b. Using a doubly linked list is more efficient than an array when accessing the ith element of a structure. c. A dynamically resizable array is another name for a linked list. d. Any type of list tends to be better than an array when there are a set number of maximum items known beforehand. e. If many deletions at any place in the structure were common, a linked list implementation would likely be preferable to an arrayYou are given the pointer to the head node of a linked list and an integer to add to the list. Create a new node with the given integer. Insert this node at the tail of the linked list and return the head node of the linked list formed after inserting this new node. The given head pointer may be null, meaning that the initial list is empty. Function Description Complete the insertNodeAtTail function in the editor below. insertNodeAtTail has the following parameters: SinglyLinkedListNode pointer head: a reference to the head of a list int data: the data value for the node to insert Returns SinglyLinkedListNode pointer: reference to the head of the modified linked list Input Format The first line contains an integer , the number of elements in the linked list.The next lines contain an integer each, the value that needs to be inserted at tail.
