- ] ] get_nhbr In the cell below, you are to write a function called "get_nhbr(Ist, graph)" that takes in two inputs: a list of vertices and a graph. The function is to return a list that contains the neighborhood of the vertices in 'Ist' (remember that this means you are finding the union of the individual vertices' neighborhoods). + Code + Markdown After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (get_nhbr(["A", "D"], {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E":["B","C","F"], "F":["E"]}), get_nhbr(["B", "C", "F"], {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E":["B","C","F"], "F":["E"]})) This should return ["B"] ["A", "D", "E"] Python PythonAssignment 6 - More on ListsWrite pseudo-code not Python for problems requiring code. You are responsible for the appropriate level of detail.The questions in this assignment give you the opportunity to explore a new data structure and to experiment with the hybrid implementation in Q3. 1. A deque (pronounced deck) is an ordered set of items from which items may be deleted at either end and into which items may be inserted at either end. Call the two ends left and right. This is an access-restricted structure since no insertions or deletions can happen other than at the ends. Implement the deque as a doubly-linked list (not circular, no header). Write InsertLeft and DeleteRight.2. Implement a deque from problem 1 as a doubly-linked circular list with a header. Write InsertRight and DeleteLeft.3. Write a set of routines for implementing several stacks and queues within a single array. Hint: Look at the lecture material on the hybrid implementation.Programming in C: Challenge 1: Create and Print a Doubly Linked List In class, I briefly mentioned how to create a doubly linked list (a linked list with two directions: forward and backwards). This task challenges you to create a doubly linked list of 5 nodes. If your nodes were called n1, n2, n3, n4 and n5 (which they shouldn’t, please give them original names), your list should be linked as follows: We discussed what "start" and "end" should be. Then, also in main, you will have to print the list forwards by taking advantage of the arrows pointing to the right. You will also have to print it backwards taking advantage of the arrows pointing to the left. Again, everything must be done in main. Hint: look at the way in which I printed the singly linked list in class. In other words, if your nodes had the values: n1=1, n2=2, n3=3, n4=4 and n5=5; your program should print:1 3 5 2 4 (forwards) and 4 2 5 3 1 (backwards). Please give different values to your nodes, they should not have…
- *IN C++ A handy feature of lists in Python is that you can use negative indices to get at elements starting from the very end. For example, x[-1] returns the last element in x, x[-2] returns the penultimate element, etc. Implement a struct named "PythonicIntVector" in the files "PythonicIntVector.h" and "PythonicIntVector.cpp" that supports the push_back and at methods of a vector of ints. However, be sure to add the functionality of negative indices. Don't forget that the at method still should throw exceptions for invalid indices (just like in Python)!def cartesianproduct(lst): """Takes a list of sets/frozensets and computes their Cartesian product""" cartesianproduct: This function should accept a list of one or more sets or frozensets (you can convert between them using set(fro_st) and frozenset(st)). Its output is a set or frozenset encoding the cartesian product; thus a list of two sets [{0,1}, {1,2}] could give back {(0,1),(0,2),(1,1),(1,2)}. In general, an input list of length N will yield a set of tuples of length N each.Write the code of the following functions: def fillX(pointsX,lowerLimit, upperLimit): This function receives a list pointsX and returns the same list with values between loverLimit and upperLimit. There are number of them.
- .Please do mImplement a program using Doubly LinkedList. Your doubly linked list should store information of students (Reg_no., Name, CGPA, city, age). Your program should provide following functionalities: Insert at Front Insert at Rear Insert in middle Delete from front Delete from rear Delete from middle Display all the data Data Structures in C++ Needed urgent i will thumb up herRun the code below to call the function # In[ ]: otherList = [395,2,-4,20,47,200,-50,-12] #a list for testing print ('Before sorting:', otherList) bubbleSort (otherList) print ('After sorting:', otherList) a) What are the contents of otherList after a single iteration of the outer loop of 'bubbleSort? b) How many iterations of the outer loop happen when sorting `otherList? * Then run both blocks of code (the def block and the test block) again. * Examine the output to answer the question about iterations. Create a new list below with * elements known as "yourList" - a list where you can get 'bubbleSort` to stop early (do fewer iterations). How many times did the outer loop run for 'yourList? # In[ ]: yourList = [] #fill in this list with 8 elements separated by commas print ('Before sorting:', yourList) bubbleSort (yourList) print ('After sorting:', yourList)struct node{int num;node *next, *before;};start 18 27 36 45 54 63 The above-linked list is made of nodes of the type struct ex.

- Part 1: Array list implementation: array list implements list interface plus their own functions. 1. a. Create a ArrayList of type Integer and name it as Grades. b. Create a ArrayList of type String and name it as Students. c. Create a ArrayList of type Double and name it as Results. 2. Add the following values to the array List using add function 30, 40,80 ,100,70,100,10,100,10 Print the size of the array list using size () function. 3.Search for 100 in the array list, if you find it, print a message that “those grades are perfect”. Use only contains function. 4. Repeat the step 3 using equals function. 5. Check if array list is empty or not using isEmpty() function. Print a message if it’s empty and if it’s not empty also. 6. the grade is under 20 which is outlier, remove it from the array list. 7. Print array list using System.out.println() 8. Use indexOf to print index of 80. 9. Use get function. 10. What is the difference between get and index of? 11. Print the values of the array…scheme: Q9: Sub All Write sub-all, which takes a list s, a list of old words, and a list of new words; the last two lists must be the same length. It returns a list with the elements of s, but with each word that occurs in the second argument replaced by the corresponding word of the third argument. You may use substitute in your solution. Assume that olds and news have no elements in common. (define (sub-all s olds news) 'YOUR-CODE-HERE )@6 The Reference-based Linked Lists: Select all of the following statements that are true. options: As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions. According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node. According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node. In a double-ended singly linked list, the tail reference variable provides access to the entire list. In a circular linked list, the last node references the first node.
