6. Given an random number generator rand5() that generates a uniform random integer in the range |1, 5|, design an algorithm for rand7() that generates a uniform random integer in the range |1, 7|. You can only call the API rand5(), and you shouldn't call any other AlPI. What is the expected mumber of times you call rand5()? How small can you make this expected number?

- Modify the RationalNumber class so that it implements the Comparable interface. To perfom the comparison, compute an equivalent floating point value from the numerator and denominator for both RationalNumber objects, then compare them using a tolerance value of 0.0001. Write a main driver to test your modifications. (Java)Write a java (Java 7 ) program for this :-- A new deadly virus has infected large population of a planet. A brilliant scientist has discovered a new strain of virus which can cure this disease. Vaccine produced from this virus has various strength depending on midichlorians count. A person is cured only if midichlorians count in vaccine batch is more than midichlorians count of person. A doctor receives a new set of report which contains midichlorians count of each infected patient, Practo stores all vaccine doctor has and their midichlorians count. You need to determine if doctor can save all patients with the vaccines he has. The number of vaccines and patients are equal. Input Format First line contains the number of vaccines - N. Second line contains N integers, which are strength of vaccines. Third line contains N integers, which are midichlorians count of patients. Output Format Print a single line containing ′Yes′ or ′No′. Input Constraint 1<N<10 Strength of vaccines…Write a program Minesweeper.java that takes three integer command-line arguments m, n, and k and prints an m-by-n grid of cells with k mines, using asterisks for mines and integers for the neighboring mine counts (with two space characters between each cell). To do so, Generate an m-by-n grid of cells, with exactly k of the mn cells containing mines, uniformly at random. For each cell not containing a mine, count the number of neighboring mines (above, below, left, right, or diagonal)

So, the in- sertion method has this specification: public void insert(String entry, int key);// Precondition: size( ) < CAPACITY, and the // bag does not yet contain any item// with the given key.// Postcondition: A new copy of entry has// been added to the bag, with the given key. When the programmer wants to remove or retrieve an item from a keyed bag, the key of the item must be specified rather than the item itself. The keyed bag should also have a boolean method that can be used to determine whether the bag has an item with a specified key. In a keyed bag, the pro- grammer using the class specifies a particular key when an item is inserted. Here’s an implementation idea: A keyed bag can have two private arrays, one that holds the string data and one that holds the corresponding…Create a client that produces test data by distributing objects in a manner different than uniformly, such as the following: ■ Gaussian■ Poisson■ Geometric■ Discrete Create and test assumptions about how the performance of the algorithms will be impacted by such input.
- Design a java program that simulates a checkout line at a supermarket. The line is a queue object. Customers (i.e., customer objects) arrive in random integer intervals of from 1 to 4 minutes. Also, each customer is serviced in random integer intervals of from 1 to 4 minutes. Obviously, the rates need to be balanced. If the average arrival rate is larger than the average service rate, the queue will grow infinitely. Even with “balanced” rates, randomness can still cause long lines. Run the supermarket simulation for a 12-hour day (720 minutes), using the following algorithm: Choose a random integer between 1 and 4 to determine the minute at which the first customer arrives .At the first customer’s arrival time, do the following: Determine customer’s service time (random integer from 1 to 4). Begin servicing the customer. Schedule the arrival time of the next customer (random integer 1 to 4 added to the current time). For each minute of the day, consider the following: If the next…In javascript: Page #1: Greets User 1 (The Word Chooser) and asks for their Name, a word, and the number of wrong guesses they would like to give User 2(The Guesser).User 1 then clicks the "Go" button, which leads to page 2. Page #2: Greets User 2 by telling them the word choosers name and how many guesses they have been given for the word, they initially see a "-" for each unguessed letter, and a counter with remaining bad guesses. They must also be shown previously guessed letters. There is a place for them to enter their name and to guess letters. After all guesses are done, win or lose, the page goes to: Page #3: Congratulates the user, or informs them of their failure to guess the word. This page must show: User 1 Name User 2 Name Word they were trying to guessPlease help. How to solve this on Java language by using only Dynamic Programming? Thank you. We are given a set A of integers. Check whether we can partition A into three subsets with equal sums. It is important to note that all elements should be included in the equally divided subsets; no element should be left out, and none of the elements should be repeated in the subsets.For example: A={4,7,6,2,10,7,10,2} has such a partition: {4,2,10}, {7,7,2},{6,10}Input: A set, A, of integersOutput: if we can partition A into three subsets with equal sums, print subsets otherwise present a suitable message.
- Hello, i need help with understanding Big-O. What is the execution time Big-O for each of the methods in the Queue-1.java interface for the ArrayQueue-1.java and CircularArrayQueue-1.java implementations? Short Big-O reminders: Big-O is a measure of the worst case performance (in this case execution time). O(1) is constant time (simple assignment statements) O(n) is a loop that iterates over all of the elements. O(n2) is one loop nested in another loop, each of which iterates over all the elements. If a method calls another method, what happens in the called method must be taken into consideration. Queue.java public interface Queue<E> { /** * The element enters the queue at the rear. */ public void enter(E element); /** * The front element leaves the queue and is returned. * @throws java.util.NoSuchElementException if queue is empty. */ public E leave(); /** * Returns True if the queue is empty. */ public boolean…I am having an error in the following java method. pipeline <- javaMethod('createCoreNLP', 'edu.stanford.nlp.pipeline.StanfordCoreNLP', 'en') Error in javaMethod("createCoreNLP", "edu.stanford.nlp.pipeline.StanfordCoreNLP", :could not find function "javaMethod" Here is my codes: Sys.setenv(JAVA_HOME='C:\\Program Files\\Java\\jdk-18.0.1.1')library(rJava) library(coreNLP)options( java.parameters = "-Xmx6g" ) #Set up the environment for Java#Init Java#.jinit(classpath = c(file.path(Sys.getenv('HOME'), '/Downloads/stanford-corenlp-full-2018-02-27/stanford-corenlp-3.9.1.jar'), file.path(Sys.getenv('HOME'), '/Downloads/stanford-corenlp-full-2018-02-27/slf4j-simple.jar'), file.path(Sys.getenv('HOME'), '/Downloads/stanford-corenlp-full-2018-02-27/slf4j-api.jar')), boundaries = '- Xmx5120m').jinit(classpath = c(file.path(Sys.getenv('HOME'), '~/IS 688/stanford-corenlp-4.4.0/stanford-corenlp-4.4.0.jar'), file.path(Sys.getenv('HOME'), '~/IS 688/stanford-corenlp-4.4.0/slf4j-simple.jar'),…Implement an ADT that can used as a Tic-Tac-Toe game board.
