- Write a recursive method that takes as parameter as array of type double (num) and the length of the array (len). The method should display the square root of numbers that are greater than 10.0 in the array. The method prototype is: public static void display(double [] num, int len); You may use sqrt method that is defined in the Math class.java 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.Write java code that recursively calculates the Sum of the array cells. Program requirements: Create an array named MyArr and initialize it as follow: 243 88 31 19 27 81 100 6 10 5 1- Write a method named ArrSum that recursively calculates the Sum of the numbers in the Array and returns the Sum of the numbers. Hint: Method with 1 parameter (the Array) that returns 1 value (the Array's Sum). 2- Write a method named Display that displays the Array contents and Sum of the numbers. Hint: Method with 2 parameters (the Array) and Sum with no returns (void) 3- Write a method named ArrSort using the bubble sort to sort Array. 4- Your program output format must be the same as the following: =>> Array Summation Array: 5 6 10 19 27 31 81 88 100 243 Sum: 610 =>> End of the Program Be sure to add Documentation / Comments
- java Write a recursive method largestDigitthat accepts an integer parameter and returns the largest digit value that appears in that integer. Your method should work for both positive and negative numbers. If a number contains only a single digit, that digit's value is by definition the largest. The following table shows several example calls: Call Value Returned largestDigit(14263203) 6 largestDigit(845) 8 largestDigit(52649) 9 largestDigit(3) 3 largestDigit(0) 0 largestDigit(-573026) 7 largestDigit(-2) 2 Obey the following restrictions in your solution: You may not use a String, Scanner, array, or any data structure (list, stack, map, etc.). Your method must be recursive and not use any loops (for, while, etc.). Your solution should run in no worse than O(N) time, where N is the number of digits in the number.URGENT JAVA Write a Java method that takes two 2 dimensional int arrays (a and b) and a 2 dimensional boolean array (c) where all three arrays have the same size. Your method should return an array (result) such that, if a partic- ular element in c is true, then the corresponding (same indexed) element in result must be the multiplication of the the corresponding elements of a and b. If the element in c is false, then the the corresponding element in result must be the negative of multiplication of the the corresponding element in a and b. For example ifa = {{1,2,3},{4,5}},b = {{1,2,1},{0,2}} andc = {{true,false,true},{false,true}}, then the result should be result={{1, -4, 3}{0, 10}}.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.
- 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.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.Pseudocode for Java code Write the algorithm in pseudocode for a method that accepts three parameters: an integer array, an integer representing the number of valid values in the array, and an integer representing a factor. The method will count the number of valid values in the array that are multiples of the factor and will return the count. There is a Java operator that might be very helpful in solving this problem. Testing Above problem: Assuming that the first two parameters are an array containing 4, 10, 15, 12, 8, 20, 100, 25, 32, 7, 28, and 48 and the number 12, come up with three good test cases for the factor and the return value. factor numMultiples
- PYTHON: This exercise is a variation on "instrumenting" the recursive Fibonacci program to better understand its behavior. Write a supporting method that counts how many times the fib function is called to compute fib (n) where n is a user input. Hint: To solve this problem, you need an accumulator variable whose value "persists" between calls to fib. You can do this by making the count an instance variable of an object. Create a FibCounter class with the following methods: _init_(self) Creates a new FibCounter, setting its count instance variable to 0. getCount(self) Returns the value of count. fib(self, n) Recursive function to compute the nth Fibonacci number. It increments the count each time it is called. resetCount(self) Sets the count back to 0.Java: Write a recursive method that finds and returns the sum of the elements of an int array. Also, write a program to test your method.Q1. Produce a method that reads in a set of values (double) from the user and returns them. Use this header: public static double[] getNumsFromUser (String msg1, String msg2) The implementation of the method should start with a message to input the total number of array elements, followed by a message to enter all the array elements. The method returns the array of elements. The two strings msg1 and msg2 that are passed to the method as parameters will be the two messages that tell the user what to do. In the main class, use the following program outline to test this method: public class Q1 { public static void main(String[] args) { String s1 = "Enter number of students: "; String s2 = "Enter student grades: "; double[] numbers = getNumsFromUser(s1, s2); System.out.println(Arrays.toString(numbers)); public static double[] getNumsFromUser(String msg1, String msg2){ //your code goes here } Sample run Enter number of students: 4 Enter student grades: 12.5 23 11.5 27 [12.5, 23.0, 11.5,…
