X173: array220 Given an array of int s, compute recursively if the array contains somewhere a value followed immediately by that same value times 10. We'll use the convention of considering only the part of the array that begins at the given index.In this way, a recursive call can pass index + 1 to move down the array. The initial call will pass in an index position of 0. Your Answer: 1 public boolean array220(int[] nums, int index) 2{ 4}

The solution must be recursive. 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.
getSumEven Method; public static int getSumEven(int[] array) Returns the sum of even values (if any) present in the array parameter. You can assume array is not null. You may only use one auxiliary function. Your implementation must be recursive and you may not use any loop construct. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: array - Returns: Sum of even values
Method Implementation Design and implement a method to swap the first and the last element of an array. For example, 1 4 9 16 25 would be transformed into 25 4 9 16 1. Important: You don’t need to test this method in main(). You don’t need to initialize the array. You don’t print out the values in the method. All you need to do is swap the first with the last element. pubilc static void swapFirstLast(int [] arr) {
can you please convert this python code into java? Python code is as shown below: # recursive function def row_puzzle_rec(row, pos, visited): # if the element at the current position is 0 we have reached our goal if row[pos] == 0: possible = True else: # make a copy of the visited array visited = visited[:] # if the element at the current position has been already visited then it's a loop. # as then its not possible to reach the last element, set possible to False if visited[pos]: possible = False else: # set visitied for the element as True visited[pos] = True possible = False # if its possible to move left then recurse in the left direction if pos - row[pos] > 0 and row_puzzle_rec(row, pos - row[pos], visited): # return immediately if the goal is reached return True # if its possible to move right then recurse in…
Mina always wants things to be sorted. She loves perfection in work and doesn't worry about time. Her brother gifted her some boxes with different sizes. Now she needs your help to sort it. You're given n boxes with different sizes and your task is to sort the boxes in ascending order of size. You should recursively partition the array with a number p so that all the elements greater than p are to its right and all the elements lower than p to its left to sort the boxes. Make sure you are giving a solution that doesn't exceed the time complexity of O(n^2), but on average has complexity of O(nlogn) a. Which algorithm will you suggest to Mina? Explain if your algorithm is stable or unstable with appropriate example b. Show the step by step simulation of your algorithm on the boxes of size 5, 9, 10, 3, 15, 12, 6, 20, 9, 13, 3, 10, 1, 2. c. Give an example of box sizes when it will be worst case and when it will be the best case for this algorithm.
Problem 1: Create a Java class RecursiveMethods.java and create the following methods inside: ALL THE METHODS NEED TO BE COMPLETED RECURSIVLY. NO LOOPS ALLOWED. oddEvenMatch Rec: 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. After completing the methods, use the main method to test them. You can hard code the tests.
Without using Java environment Write a recursive function with two parameters: an array of ints and the number of elements in the array. The function will return the sum of all positive values in the array. Do not add any negative array elements to the sum. You can add another parameter to the function if you wish.
8. Repetition Use Python Language Write a method that takes in an array as a parameter and counts the repetition of each element. That is, if an element has appeared in the array more than once, then its 'repetition' is its number of occurrences. The method returns true if there are at least two elements with the same number of 'repetition'. Otherwise, return false. Input: {4,5,6,6,4,3,6,4} Output: True Explanation: Two numbers repeat in this array: 4 and 6. 4 has a repetition of 3, 6 has a repetition of 3. Since two numbers have the same repetition output is True. Input: {3,4,6,3,4,7,4,6,8,6,6} Output: False Explanation: Three numbers repeat in this array:3,4 and 6 .3 has a repetition of 2, 4 has a repetition of 3, 6 has a repetition of 4. Since no two numbers have the same repetition output is False.
Write a recursive method that returns thelargest integer in an array. Write a test program that prompts the user to enter alist of eight integers and displays the largest element.
write a recursive method that will sum up all elements in an array and returm the result. name the method as arraySum
Design and implement a method to double all elements of an array. Important: You don’t need to test test method in main(). You don’t need to initialize the array. pubilc static void doubleElements(int [] arr) { }
PLEASE SOLVE IN JAVA without using arrays list just simple array FAST PLEASE Write a java method that receives two arrays of integers called arr1 and arr2 and then returns the number of rotations to the left or to the right so that arr1 and arr2 becomes the same. if not possible the method returns your student ID number.
