A dog is running up a staircase with n steps and can hop either 1 step, 2 steps, or 4 steps at a time. Implement a method to count how many possible ways the dog can run up the stairs. Note that for n = 1, 2, and 4 there are 1, 2, 6 ways to run up the stairs, respectively. [Adapted from CCI, pg. 150]
Write a method to return the reverse order for a list of space separated words. Example: "A sample sentence is required" would return "required is sentence sample A" I have this to start: class Solution: def reverse_words(self, input): # Your code goes here These are the tests: from solution import Solution import unittest class SolutionTests(unittest.TestCase): def test1(self): solution = Solution() self.assertEqual(solution.reverse_words("the quick brown fox"), "fox brown quick the") if __name__ == '__main__': unittest.main() Any help would be appreciated!
You have a card on which the letter J is written on one side and K on the other. You want to seeall of the possible ways the card will land if you drop it n times. Write a recursive method thatprints each session of dropping the cards with J's and K's. For example if you drop it 4 times in agiven session, all possible ways to drop it are as follows (in exactly the specified order): (java code)

In java, Write a method checks if a given matrix is a unit matrix. An N x N unit matrix is a matrix of N rows and N columns where all the diagonal elements are ‘1’s and all the remaining elements are ‘0’s. The method should take a 2D array of integers as argument and return a Boolean which is true/false depending on whether the matrix corresponding to the 2D array is a unit matrix or not. Test the method in the ‘main’ method. For problems asking for 'methods', you need to write the method, and the 'main' method which is used as a 'driver' to test the given method.
Implement a method rand7 () given rand S (). That is, given a method that generates a random number between O and 4 (inclusive), write a method that generates a random number between O and 6 (inclusive)
Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain less than 20 words. Ex: If the input is: 5 hey hi Mark hi mark the output is: hey 1 hi 2 Mark 1 hi 2 mark 1 Hint: Use two arrays, one for the strings, another for the frequencies. Your program must define and call a method:public static int getFrequencyOfWord(String[] wordsList, int listSize, String currWord)

Java. Write a method boolean checkTTT(char[][] TTTboard) to show whether there is a winner. It returns true if the Tic Tac Toe game has only exact one winner (does not matter if 'O' or 'X' wins). It returns as false if the Tic Tac Toe game does not have a winner or it has more than one winners (Both ‘X’ and ‘O’ win). We claims that ‘X’ (or ‘O’) wins on the board of size n if there are n consecutive ‘X’ (or ‘O’) showing up in a row, or a column, or one of the diagonals.
Java program Write and test a void method called inOrder() that takes three strings and prints them out in the correct alphabetical order. For example the call of inOrder("abc", "mno", "xyz") will print out the values in the order abc -> mno -> xyz. However the call of inOrder("xyz" , "mno", "abc") will also print abc -> mno -> xyz.. Make sure to test your method, with at least 5 different input variations.
Please ASaP. Complete method printPopcornTime(), with int parameter bagOunces, and void return type. If bagOunces is less than 2, print "Too small". If greater than 10, print "Too large". Otherwise, compute and print 6 * bagOunces followed by " seconds". End with a newline. Example output for ounces = 7: 42 seconds import java.util.Scanner; public class PopcornTimer {public static void printPopcornTime(int bagOunces) { /* Your solution goes here */ } public static void main (String [] args) {Scanner scnr = new Scanner(System.in);int userOunces; userOunces = scnr.nextInt();printPopcornTime(userOunces);}} .
We were given the following code to solve a Pentomino puzzle, several methods might need to be added or editted to solve the problem. The program should take in an input of 3 4 5 6 for 3x20 4x15 5x12 6x10 grids. Then output the number of correct solutions for them (respectively its 2, 368, 1010, and 2339) import java.util.ArrayList;import java.util.LinkedList;import java.util.List; public class DLX { class DataNode { DataNode L, R, U, D; ColumnNode C; public DataNode() { L = R = U = D = this; } public DataNode(ColumnNode c) { this(); C = c; } DataNode linkDown(DataNode node) { node.D = this.D; node.D.U = node; node.U = this; this.D = node; return node; } DataNode linkRight(DataNode node) { node.R = this.R; node.R.L = node; node.L = this; this.R = node; return node;…
