- Recursive Power MethodWrite a method called powCal that uses recursion to raise a number to a power. The method should accept two arguments: The first argument is the exponent and the second argument is the number to be raised (example” powCal(10,2) means 210). Assume that the exponent is a nonnegative integer. Demonstrate the method in a program called Recursive (This means that you need to write a program that has at least two methods: main and powCal. The powCal method is where you implement the requirements above and the main method is where you make a method call to demonstrate how your powCal method work).arrow_forwardLab Goal : This lab was designed to teach you more about recursion.

- The enum class construct: Select one: a. does not require one to write anything in front of an enumeration value-name b. requires one to use the name of the enumeration, followed by "::" (colon-colon), before each name whenever the enumeration's value-name is used c. requires one to use the name of the enumeration, followed by "." (period), before each name whenever an enumeration's value-name is usedarrow_forward3-The following pattern of numbers is called Pascal's triangle. 1 1 1 14 641 The numbers at the edge of the triangle are all 1, and each number inside the triangle is the sum of the two numbers above it.

- Rolling Dice Simulator [Java Assignment]Objective: Create a Java program that rolls two dice and displays the results. The program should have two Java classes: one for a single die and another for a pair of dice. Assignment Details: User Input: Ask the user to specify the number of sides they want on each die. Ensure that the user's input is within a reasonable range. Dice Rolling: Simulate rolling the dice using Math.random() based on the user's chosen number of sides. Display the sum of the values rolled, e.g., "5 + 3 = 8." Special Combinations: If the dice roll results in combinations of 2, 7, or 12, print special messages: "1 + 1 = 2 snake eyes!" "3 + 4 = 7 craps!" "6 + 6 = 12 box cars!" Main Method: In the main method, create a pair of dice, roll them, and display the results. Allow the user to decide whether to continue rolling the dice or exit the program. Additional Features: You are welcome to add more features or enhancements to the program if desired.…arrow_forwardTopics Classes Methods Data Collections: Lists, Tuples, and Dictionaries String Manipulation Chess Objective: practicing with classes, instance methods, data collections, loops, if and elif statements, and string methods Description In this assignment you will write a program that shows the valid moves of chess pieces. Your program will draw a board with 64 squares using the traditional layout, next ask the user to choose a move, and then, depending on the user's choice, redraw the board with the selected chess piece and its valid moves. Please see the examples of valid moves of chess pieces and the traditional chess board layout below: At the beginning, your program should draw an empty chess board and prompt the user to enter a move: Welcome to the Chess Game! a b c d e f g h +---+---+---+---+---+---+---+---+8| | | | | | | | |8 +---+---+---+---+---+---+---+---+7| | | | | | | | |7 +---+---+---+---+---+---+---+---+6| | | | | |…arrow_forwardC++ language Write a menu driven program which has following options:1. Factorial2. Prime or not3. Odd or even4. ExitOnce a menu is selected, the appropriate action should be taken and once this action is finished,the menu should reappear. Unless the user selects the ‘Exit’ option the program should continueto work.Note: Consider array of random numbers from user to find Prime Numbers/Odd/Even and userentered value for factorial.arrow_forward
- Magic Number of coding-:A number is said to be a magic number,if summing the digits of the number and then recursively repeating this process for the given sumuntill the number becomes a single digit number equal to 1. Example: Number = 50113 => 5+0+1+1+3=10 => 1+0=1 [This is a Magic Number] Number = 1234 => 1+2+3+4=10 => 1+0=1 [This is a Magic Number] Number = 199 => 1+9+9=19 => 1+9=10 => 1+0=1 [This is a Magic Number] Number = 111 => 1+1+1=3 [This is NOT a Magic Number].arrow_forwardclass Main { // this function will return the number elements in the given range public static int getCountInRange(int[] array, int lower, int upper) { int count = 0; // to count the numbers // this loop will count the numbers in the range for (int i = 0; i < array.length; i++) { // if element is in the range if (array[i] >= lower && array[i] <= upper) count++; } return count; } public static void main(String[] args) { // array int array[] = {1,2,3,4,5,6,7,8,9,0}; // ower and upper range int lower = 1, upper = 9; // throwing an exception…arrow_forwardT/F The body of a method may be emptyarrow_forward
