- Write a Java method (do not write a class, only the method) with the following signature: Return type: void Parameters: 2D integer array Name: printDiagonal Implement the method code that will print out the values of the 2D array along the Diagonal from left to right. For example, if the array had the following values: 56 78 98 21 33 55 98 44 11 The method should print to the console: 56,33,11 The above 2D array example is only given for you to understand the problem Do not hard code the values in your solution or assume the array is the same as the given data. Your method should work for all 2D integer arrays.Write a java program that uses an ArrayList object to store the following set of names in memory: [Steve, Tim, Lucy, Pat, Angela, Tom] Now write some more code so that the same ArrayList object is augmented with the name 'Steve' after the name 'Lucy' After the ArrayList object has been augmented with the new name, display the original and new lists on the console (as shown below), to verify that the new name is positioned correctly in the list.The Java code provides a Class named Function in Function.java that has a static method named f that takes a double argument and returns the value of . It also has a static method named fprime that takes a double argument for x and returns the value of the slope of f(x). The slope of f(x) can be calculated as . Implement this method. public class Function { public static double f(double x) { return Math.pow(x,3) - 3 * x; } public static double fprime(double x) { // your code goes here } }

The point of the solver class is the solve method which takes a board/puzzle configuration represented as a 2D array of bytes and returns a byte array containing a minimal sequence of moves that will lead to the solved board. The 2D array of bytes is “triangular” and represents a valid board configuration. Namely, the 2D array has 5 rows (0 – 4) and the size of every row is 1 more than its index.The array contains one 0, five 1s, four 2s and five 3s. The solve method then returns an array of bytes representing a minimal sequence of moves that solves the puzzle. In other words, if the numbers from the returned array are used in order as inputs to the move method on the Board object representing the initial configuration, the resulting board configuration represents the solved board. If the input to the solve method is a board configuration that is already solved, then solution requires no moves and an array of size 0 must be returned. import java.util.Arrays;…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.
