In Java!!!. Design and implement a recursive version of a binary search. For the recursive version, instead of using a loop to repeatedly loop for the target value, allow each call to a recursive method check one value. If the value is not the target, refine the search space and call the method again. The indexes that define the range of viable candidates can be passed to the method. The base case is either finding the target value or running out of data to search. Design the program to work for on an array of sorted String objects.

- Make a recursive method for factoring an integer n. First, find a factor f, then recursively factor n / f. This assignment needs a resource class and a driver class; these two classes will need to be in two separate files. The resource class will contain all of the methods and the driver class only needs to call the methods. The driver class needs to have only 5 lines of code. The code needs to be written in Java.Profile the performance of the memoized version of the Fibonacci function defined in Project 6. The function should count the number of recursive calls. State its computational complexity using big-O notation, and justify your answer. The fib function header has been modified to include the counter as the second parameter. Define the Counter class, it should have three methods: __init__, increment, and __str__. When an instance of the Counterclass is passed as a parameter, the countproperty of that instance should be incremented based on the number of recursive calls. The __str__ method should return the countproperty's value as a string. Please can you change the solution to this problem here, because this is wrong.

- Implement a recursive function void deleteMax() on the IntList class (provided). The function will delete from the IntList the IntNode containing the largest value. If there are multiple nodes containing this largest value, only delete the 1st one. Be careful not to cause any memory leaks or dangling pointers. You may NOT use any kind of loop (must use recursion). You may NOT use global or static variables. You may NOT use any standard library functions. Ex: list: 5->7->1->16->4->16->3 list.deleteMax(); list: 5->7->1->4->16->3 IntList.h #ifndef __INTLIST_H__#define __INTLIST_H__ #include <ostream> using namespace std; struct IntNode {int value;IntNode *next;IntNode(int value) : value(value), next(nullptr) {}}; class IntList { private:IntNode *head; public: /* Initializes an empty list.*/IntList() : head(nullptr) {} /* Inserts a data value to the front of the list.*/void push_front(int val) {if (!head) {head = new IntNode(val);} else {IntNode…Design and implement a service that simulates PHP loops. Each of the three loop variants should be encapsulated in an object. The service can be controlled via a parameter and execute three different simulations. The result is returned as JSON. The input is an array consisting of the letters $characters = [A-Z]. -The For loop should store all even letters in an array.-The Foreach loop simulation is to create a backward sorted array by For loop, i.e. [Z-A] .-The While loop should write all characters into an array until the desired character is found. Interface:-GET Parameter String: loopType ( possible values: REVERSE, EVEN, UNTIL )-GET parameter String: until (up to which character) Output:JSON Object: {loopName: <string>, result: <array> }Use C#. Chapter 6 discussed the predefined IndexOf() method of an array; the method takes two parameters, the whole array and an element to search. The method returns the index of the element if found, and -1 if not found. Now, you are asked to write a program that has a method FindMatch() that does exactly the same thing: 1) The Main() calls FindMatch(). 2) FindMatch() takes two parameters: 1) the whole array of integer test scores { 85, 98, 100, 73, 67, 82, 92, 87 }, and 2) an element to search from users input. 3) FindMatch() returns the index of element if found back to the Main(), and -1 if not found. The method should not use IndexOf() to do the search. 4) The program displays either the index or -1 in the Main(). Sample output (from Microsoft Visual Studio) as shown below
- I already have the code for the assignment below, but the code has an error in the driver class. Please help me fix it. The assignment: Make a recursive method for factoring an integer n. First, find a factor f, then recursively factor n / f. This assignment needs a resource class and a driver class. The resource class and the driver class need to be in two separate files. The resource class will contain all of the methods and the driver class only needs to call the methods. The driver class needs to have only 5 lines of code The code of the resource class: import java.util.ArrayList;import java.util.List; public class U10E03R{ // Recursive function to // print factors of a number public static void factors(int n, int i) { // Checking if the number is less than N if (i <= n) { if (n % i == 0) { System.out.print(i + " "); } // Calling the function recursively // for the next number factors(n, i +…Implement a city database using ordered lists. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x and y coordinates. Your database should allow records to be inserted, deleted by name, and searched by name. Another operation that should be supported is to print all records within a given distance of a specified point/coordinate. The order of cities should be alphabetically by city name. Implement the database using: an array- based list implementation. By using JAVA.Design and implement a program that implements Euclid’s algorithm for finding the greatest common divisor of two positive integers. The greatest common divisor is the largest integer that divides both values without producing a remainder. In a class called DivisorCalc, define a static method called gcd that accepts two integers, num1 and num2. Create a driver to test your implementation. The recursive algorithm is defined as follows:gcd (num1, num2) is num2 if num2 <= num1 and num2evenly divides num1gcd (num1, num2) is gcd(num2, num1) if num1 < num2gcd (num1, num2) is gcd(num2, num1%num2) otherwise
- Create a Java class RecursiveMethods.java and create the following methods inside: ALL THE METHODS NEED TO BE COMPLETED RECURSIVLY. NO LOOPS ALLOWED. - oddEvenMatchRec: the method takes an integer array as a parameter and returns a boolean. The method returns true if every odd index contains an odd integer AND every even index contains an even integer(0 is even). Otherwise it returns false. - sumNRec: The method takes an integer array A and returns the sum of all integers in the parameter array. - nDownToOne: Takes an integer n and prints out the numbers from n down to 1, each number on its own line. - inputAndPrintReverse: Inputs integers from the user until the user enters 0, then prints the integers in reverse order. For this method, you may NOT use an array or any type of array structure, in other words, you may not use any structure to store the user input.Part 4. sum Method Define a method in simpy named sum. Its purpose is to compute and return the sum of all items in the values attribute. You are encouraged to use Python's built-in sum function to assist in the implementation of your sum method. Doing so is illustrative of a pattern called delegation, where the implementation of some algorithm is delegated to existing algorithm. It should take no arguments and return a float. ones = Simpy([1.0, 1.0, 1.0]) print("Actual: ", ones. sum(), Expected: 3.0") one_to_nine = Simpy([]) one_to_nine.arange(1.0, 10.0) print("Actual: ", one_to_nine.sum(), - Expected: 45.0") PythonJava problem implement this specification. In addition, while Scanner input and System.out output will take place only in the main method, all solitaire game simulation and computation of the first player win probability estimate should take place in a method getAdvantage that takes an integer parameter for the number of games to simulate, and returns a double-precision floating-point first player win probability. The main method will read the desired number of simulations, call method getAdvantage with that number, and report the returned number in the specified format. Specification: First-Player Advantage Pig is a folk jeopardy dice game with simple rules: Two players race to reach 100 points. Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions: roll - If the player rolls a 1: the player scores nothing…
