- python exercise: Write a Python function called get_top_students that takes the list of dictionaries as input and returns a dictionary containing the name and GPA of the top two students in the list. Each dictionary has the following keys: "name", "age", "major", and "gpa".python LAB: Subtracting list elements from max When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. Write a program that adjusts a list of values by subtracting each value from the maximum value in the list. The input begins with an integer indicating the number of integers that follow.What does the following error message normally mean? IndexError: list index out of range Select one: а. This error normally indicates that you have tried to access an element of a list that doesn't exist. O b. This error normally means that you have used the range() function incorrectly. С. This error normally means that you have used a list where you should have used a tuple. d. This error normally means that you used too many lines of code in your program.
- In C#: Run the following console application. This program should produce the union of two sets, but has several errors. Use a variety of debugging techniques to locate and correct the errors. NOTE: A set is a collection of like elements that does not contain any duplicates. The union of two sets is the set that contains all the elements in both sets. Formally: A union B = {x : x Î A or x Î B}read: A union B is the set of all x such that x is in A or x is in B Example: A = {1,2,3,4,5} and B = {2,4,6,8}, then A union B = {1,2,3,4,5,6,8} (notice, no duplicates!) Debug the program. When you find an error, comment out the offending line, give an explanation of the error, write a corrected line, and include a screenshot of your program running with successful output. Submit the modified files and screenshots of any breakpoints you use. Program using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace…17. The following function takes a parameter that is a list of integers; the list has at least one element. It is supposed to find the integer that is the largest and find the position of that integer in the list. The function has two incorrect lines of code that make the function compute the results incorrectly. Several lines are highlighted (bold, underlined) which COULD be incorrect. In the following questions, choose the correct line of code that should be in the function. 1 def findlarge(intlist): 2 largest = 0 3 pos = 0 for i in range(1,len(intlist)): if largest > intlist[i: 4 5 largest = intlist[i] pos = i return (largest, pos) 8 Select one of the following to correct a line of code in the function. a. Line 2 should be: largest = -1 b. Line 2 should be: largest = intlist[0] c. Line 4 should be: for i in range(0,len(intlist): %3D d. Line 4 should be: for i in range(1,len(intlist)-1): e. Line 8 should be: return largest 18. Select one of the following to correct a line of code in…Help make a C++ program that:1. Queries the user for the name of a file of text.2. Opens the file, and maintains two lists: one list for words beginning with the letter"D" or "d", and a second list for words beginning with any other letter. Each listmust maintain words in alphabetical order.3. Each node in the list must contain the word and the number of times that the word appears.4. Display (a screen at a time) each of the lists showing the alphabetized list of words and thenumber of times that each appears. Please have the main function as the first function in the program. Please make the least amount of functions as possible. Like for the file input have the file error thing in the same function. And please add comments throughout the code.
- @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.] ] 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 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 array
- Task 5: Unscramble You will write a program that takes in 2 files: a dictionary file and a file listing jumbled words. Your binary will be called unscramble and will be run using unscramble The file contains a bunch of scrambled words, one word per line. Your job is to print out these jumbles words, 1 word to a line. After each jumbled word, print a list of real dictionary words that could be formed by unscrambling the jumbled word. The dictionary words that you have to choose from are in the file. As an example, the starter package contains two sample input files and the result should look as follows. The order that you display the dictionary words on each line can be different; however, the order that you print out the jumbled words should be identical to the order in your input. The sample out below is skipping a few lines to save handout space (your output must not omit these lines). nwae: wean anew wane eslyep: sleepy rpeoims: semipro imposer promise ettniner: renitent.…Assume the following list exists: names = ['Chris', 'Katie', 'Joanne', 'Kurt'] Write a statement that uses a dictionary comprehension to create a dictionary named X in which each element contains the length of a name from the list as the key, and the corresponding name's initial character as its value.
