Write a recursive algorithm mypowerlist (n) that, given a nat- ural number n as input, returns the "powerlist" (i.e. the power- set expressed as a list) of {1, ...,n}. So the output of mypowerlist (2) should be the following list of sets: [set(),{1}, {2},{1,2}]. Hint: it is obvious what the solution is for n=0. For n+1 note that there are two kinds of subset: those containing n+1, and those not. The latter can be obtained immediately by calling mypowerset (n). How can you obtain the first group?

Implement the interface DictionaryInterface<string, string> to create a class of glossaries. A glossary is a dictionary of specialized terms and their corresponding definitions. Represent the glossary as a collection of 26 sorted lists, one list for each letter of the alphabet. Each entry—which consists of a term and its definition—in a glossary is stored in the sorted list corresponding to the term’s first letter. Thoroughly test your class using a text file of terms and definitions as data for your glossary. Java program
Please answer quick. In python The FlipList class defined below is intended to be identical to a list, except that the append method only adds new elements to the back of the list when the length of the list is odd. When the length is even, append should instead add the new element to the front of the list. class FlipList(list): def append(self, item): if len(self) % 2 == 0: self.insert(0, item) else: _________ Fill in the blank with a line of code such that FlipList works as described above.
You are the manager of the train depot. One of your tasks is to efficiently order the train cars so that it is easy to attach and detach them. In this assignment, you will implement Train Cars program that reads car details from the file called car.txt (given) and stores them in a LinkedList data structure. Cars in the train are linked in a specific order. Each car in the train contains various materials that must be attached and detached in the most efficient manner possible. Each car ( node of type Car) has a stop number, factory name, material name. Stop number – determines which stop the car must be detached, use this to order the train cars. They should be ordered either in increasing or decreasing stop numbers. Factory Name – name of the factory at which the car must be detached Material Name – name of the material being transported in the car. For example, the Jiffy Mix plant at stop 2 needs sugar, flour, cornmeal, etc. Write the program to perform each operation…
Implement unique method that takes an ArrayList as input and returns an ArrayList withexactly a single occurrence of each element from the input list. For example, if the input listcontains 5, 6, 7, 6, 3, 5, 5, 4 then the output list should have 5, 6, 7, 3, 4.Note: (1) You may assume that the ArrayList has a specific type of elements in it. In the class, we assumedit to have String type values. (2) You may only work with ArrayList(s).

Create a DeleteDuplicatesclass which consists of a deleteDuplicates method which takes the nums list as its parameter. Implement the deleteDuplicates method: Check if the input list is null or empty, and return an empty list if so. Initialize a pointer i to keep track of the unique elements. Use a for loop to Iterate through the list using another pointer j which starts at j=1 and goes until j=nums.size(); If the current element at j is not equal to the previous element at i using !nums.get(i).equals(nums.get(j), increment i and set the current element at j to the new position at i using nums.set(i, nums.get(j)). After the for loop ends, return the sublist from the beginning to i + 1, as this will contain all unique elements. Call the deleteDuplicates method with the sample list as argument: Call the deleteDuplicates method and pass the nums list as argument Store the result in a variable result Print the result to the console. Input: [1, 1, 2, 3, 3,…
Develop a program in C++ that will implement a Josephus Circle using circular linked list. There are n people standing in a circle waiting to be executed. The counting out begins at some point in the circle and proceeds around the circle in a fixed direction. In each step, a certain number of people are skipped and the next person is executed. The elimination proceeds around the circle (which is becoming smaller and smaller as the executed people are removed), until only the last person remains, who is given freedom. Given the total number of persons n and a number m which indicates that m-1 persons are skipped and mth person is killed in circle. The task is to choose the place in the initial circle so that you are the last one remaining and so survive. ***Using #include <iostream>
Implement a Python program that reads a list of integers from the user, removes any duplicate elements, and then prints the modified list. The program should maintain the original order of elements while removing duplicates.
how would you do this in a simple way? this is for a non graded practice lab
Consider an ADT list of integers. In JAVA, write a method that computes the maximum of integers in the list aList. The definition of your method should be independent of the list's implementation. Implement a method swap but remove the assumption that the ith and jth items in the list exist. Throw an exception ListIndexOutOfBoundsException if i or j is out of range.

How do I code the interfaces, classes and JUnit 4 tests in java? this is all the information given below: A sentence in English is made of several words in a particular sequence. You must represent such a sentence as a list of words. Much like the list example we saw in class, this one is made of nodes (represented by a Sentence interface). There is one word per node, called WordNode. The sentence may also contain zero or more punctuation marks, which are represented by a PunctuationNode. The end of the sentence is denoted by a special empty node, called EmptyNode. Define the following operations for such a list of words: A method getNumberOfWords that computes and returns the number of words in a sentence. The punctuation does not count as a word. This method should answer/return an int. A method longestWord that determines and returns the longest word in a sentence. The word returned is just the word, and should not begin or end with punctuation. If the sentence contains no…
