JAVA Task, by using ArrayList The program reads manatee names from the standard input stream and from time to time prints a sorted portion of the list of names. All the manatee names in the input are given in the order in which the necropsy was performed. You can imagine a unique timestamp associated with each necropsy. The names are not necessarily unique (many of the manatees have the same name). Interspered in the standard input stream are queries that begin with the question mark character. Queries ask for an alphabetical list of manatee names to be printed to the standard output stream. The list depends only on the names upto that point in the input stream and does include any manatee names that appear in the input stream after the query. The list does not contain all the names of the previous necropsies, but only a selection of them. A query provides the names of two manatees, say A and B. The response to the query drops necropsies performed before the first named A and all the…
I am writing a method to remove the first element in a doubly linked list. However I am supposed to throw an exception when the list is empty. When I test my class I keep getting "testRemoveFirst caused an ERROR: Uncompilable source code - exception Exceptions.EmptyCollectionException is never thrown in body of corresponding try statement" What does that mean and why is it not able to run?(I'm coding in Java)
Maintaining the Loop Invariant (LI & not exit & codeloop → LI): Suppose that LI (the statement of the loop invariant before the iteration) is true,the exit condition exit is not, and we have executed another iteration of thealgorithm.
def analyze_file (filename: str, pos_words: List [str], neg_words: List [str]) -> Given the name of a file, a list of positive words (all in lowercase), and a list of negative words (all in lowercase), return some interesting data about the file in a tuple, with the first item in the tuple being the positivity score of the contents of this file, and the rest of the item: being whatever else you end up analyzing. (Helper functions are highly encouraged here.) How to calculate positivity score: For every word that is pos itive in the file (based on the words in the list of positive words) add 1 to the score. For every negative word (based on the list of negative words), subtract 1 from the score. Any neutral words (those that do not appear in either list) do not affect the score in any way. pass
What is the best way to implement a dynamic array if you don't know how many elements will be added? Create a new array with double the size any time an add operation would exceed the current array size. Create a new array with 1000 more elements any time an add operator would exceed the current size. Create an initial array with a size that uses all available memory Block (or throw an exception for) an add operation that would exceed the current maximum array size.
Write a java program to insert one element in a singly linked list before a given element. Your program will print the original list, request the user to put in an element to be inserted, and an element to indicate the location of the insertion, then print the final list after the insertion is done. If the element doesn't exist in the list, add the new element to the end of the list. No duplicate values are allowed to store in list. Once you done insertion operation (at least 10 element inserted) in your list, Draw a binary search tree and AVL tree ( show all rotations ) as per your inserted values . Use the following as your test cases to evaluate whether your program works correctly: If you have a linked list: 6à2à7. With user input 8 and 2. Your list should become 6à8à2à7: With user input 8 and -1. Your list should become 6à2à7à8: Let suppose your final linked list . 6à2à7à8à5à10à1à9à3
Code in R Write a while loop what prints all numbers up to 20, but it skips a collection of numbers: 3,9,13,19. A next statement is useful when we want to skip the current iteration of a loop without terminatingit. On encountering next, the R parser skips further evaluation and starts next iteration of the loop. x <- 1:5for (val in x) {if (val == 3){next}print(val)}
I ran the code and got an error. I even created a main.java file to run the test cases. Please fix the error and provide me the correct code for all parts. Make sure to give the screenshot of the output as well.
Python’s for loop allows the programmer to add or remove items in the collection over which the loop is iterating. Some designers worry that changing the structure of a collection during iteration might cause program crashes. The remedy is to make the for loop read-only, by disallowing mutations to the collection during iteration. You can detect such mutations by keeping a count of them and determining if this count goes up at any point within the collection’s __iter__ method. When this happens, you can raise an exception to prevent the computation from going forward. In the arraybag.py file complete the following in the ArrayBag class: In the __init__ method, include a new instance variable named modCount, which is set to 0. In the __iter__ method include a temporary variable named modCount, which is set initially to the value of the instance variable self.modCount. Immediately after an item is yielded within the __iter__ method, you raise an exception if the values of the two mod…
I'm trying to understand LargeIntList (Large Integers) classes for lists, I was wondering these statements or True or False? either or, can you please explain your answers? Thank you. Allows duplicate elements. Uses the LLNode class of the support package. Throws an exception if an iteration “walks off ” the end of the list. Throws an exception if an element is added when it is "full". Supports addition of elements at the front of the list, the end of the list, and anywhere in between. Can hold objects of any Java class. Has only O(1) operations, including its constructor. Provides more than one Iterator.

The Problem The Mastermind game board game is a code breaking game with two players. One player (your program) becomes the codemaker, the other the codebreaker. The codemaker (your program) creates a 4 digit secret code which is randomly generated by the supplied code below and the codebreaker tries to guess the 4 digit pattern. import randomsecretCode =[]for i in range (0,4): n = random.randint(1,9) secretCode.append(str(n)) print (secretCode) # take this out when you are playing the game for real because it is a secret The secret code pattern generated above will consist of any of the digits 1-9 and can contain multiples of the same digit. Your program should then tells the codebreaker which digits should be in their guess by displaying a sorted list of the digit characters contained in the secret code python list . Use the loopfor digit in sorted(secretCode): #display each digit on the same line for the player to see; there could be duplicate digits in the secret Prompt…
