1-Let the list have a head and a tail. That is, a pointer (have a marker) to both the beginning (first Node) of the list and the last Node. What process does Tail facilitate? 2-insert(int index, int element): adds this element to the index position. For example, if index is 4, it adds this element between index 3 and 4 in the list. The size of the list has increased by one. 3-append(int elem): Adds the element to the end of the list. The size of the list has increased by one. 4-get(int index): Returns the element at the index position of the list, no change in the list. 5-remove(int index): Returns the element at the index position of the list. This element is removed from the list and the list size is reduced by one. 6-findMin(): returns the index of the smallest number in the list. 7-findMax(): returns the index of the largest number in the list. 8-search(int elem): searches elem in the list. It returns -1 when you can't find elem's index when you find it. 9-ToArray(): Return an…

“PLEASE USE C++ IDE” 1. construct a program that will utilize the first two (2)operations of Linked List mentioned above. Your program must dothe following: 1. It must be a menu-driven program with the following choices:[A] Add Pet Name[B] Display Pet Name[C] Reverse Display[D] Delete[E] Exit SAMPLE OUTPUT: MENU[A] Add Pet Name[B] Display Pet NameIC] Reverse Display[D Delete[E] ExitEnter choice: 2. For option [A], the data that the user should add in the linkedlist are Pet Names. You have an option to use a string or achar data type. No whitespaces are needed since only one wordis used for the pet names. The program will continuously askthe user to enter pet names until letter “X” is entered. SAMPLE OUTPUT: MENUA] Add Pet Name[B) Display Pet Name[C] Reverse Display[D] Delete(E) Exit Enter choice: A Enter X to endEnter pet name to be added in the list: Brownie Enter X to endEnter pet name to be added in the list: Kitty Enter X to endEnter pet name to be added in the 1ist: x MENU[A] Add…
Create class Test in a file named Test.java. This class contains a main program that performs the following actions: Instantiate a doubly linked list. Insert strings “a”, “b”, and “c” at the head of the list using three Insert() operations. The state of the list is now [“c”, “b”, “a”]. Set the current element to the second-to-last element with a call to Tail() followed by a call to Previous()Then insert string “d”. The state of the list is now [“c”, “d”, “b”, “a”]. Set the current element to past-the-end with a call to Tail() followed by a call to Next(). Then insert string “e”. The state of the list is now [“c”, “d”, “b”, “a”, “e”] . Print the list with a call to Print() and verify that the state of the list is correct.
Q1:Write a function that returns a new list by eliminating theduplicate values in the list. Use the following function header:def eliminateDuplicates(lst):Write a test program that reads in a list of integers, invokes the function,and displays the result. Here is the sample run of the program Enter ten numbers: 2 3 2 1 6 3 4 5 2The distinct numbers are: 1 2 3 6 4 5 Q2:Write a program that reads in your Q1 Pythonsource code file and counts the occurrence of each keyword in the file.Your program should prompt the user to enter the Python source code filename. This is the Q1: code: def eliminateDuplictes(lst):newlist = [] search = set() for i in lst: if i not in search: newlist.append(i) search.add(i) return newlist a=[] n= int(input("Enter the Size of the list:")) for x in range(n):item=input("\nEnter element " + str(x+1) + ":") a.append(item) result = eliminateDuplictes(a) print('\nThe distinct numbers are: ',"%s" % (' '.join(result)))

A. Create function getData(fname:str)->ndarray that inputs data from a file into a list, then converts the list to a NumPy array of integer values and returns the array. The text file (fname) contains: integer numbers, one per line numbers are in the range 0 <= n <= 99 r * c (rows * columns) quantity of numbers, where c = r + 1. Sample follows: 15 22 65 4 78 91 7 35 60 16 99 12 The function will convert the list of numbers into a 2-dimensional NumPy array with r rows and c columns. Sample follows: [[15 22 65 4] [78 91 7 35] [60 16 99 12]] B. Create a function getSum(arr:ndarray)->int that returns the sum of all the elements within a 2-dimensional array. C. For the array example above, a sum of 504 is returned by getSum(arr). D. The mathematical functions available for NumPy arrays may not be used. Determine the sum by iterating over all the elements of the array.
Filename: runlength_decoder.py Starter code for data: hw4data.py Download hw4data.py Download hw4data.pyYou must provide a function named decode() that takes a list of RLE-encoded values as its single parameter, and returns a list containing the decoded values with the “runs” expanded. If we were to use Python annotations, the function signature would look similar to this:def decode(data : list) -> list: Run-length encoding (RLE) is a simple, “lossless” compression scheme in which “runs” of data. The same value in consecutive data elements are stored as a single occurrence of the data value, and a count of occurrences for the run. For example, using Python lists, the initial list:     [‘P’,‘P’,‘P’,‘P’,‘P’,‘Y’,‘Y’,‘Y’,‘P’,‘G’,‘G’] would be encoded as: ['P', 5, 'Y', 3, ‘P’, 1, ‘G’, 2] So, instead of using 11 “units” of space (if we consider the space for a character/int 1 unit), we only use 8 “units”. In this small example, we don’t achieve much of a savings (and indeed the…
