Overview Over the first few Long Weekly Homework assignments for this quarter, we have been building a Sudoku (Links to an external site.) solver program in pieces. This is Part 3 of the Sudoku solver series - the last in the series! In this assignment, we will add a new method to our board class called solve() which will allow us to use recursive backtracking to solve a Sudoku puzzle. Topics recursive backtracking Solving a Sudoku Puzzle What does it look like to recursively try and solve a Sudoku puzzle? Basically you try to place the values 1-9 in the empty spots of a Sudoku puzzle (move forward with a brute force attempt) until you either reach an invalid state (which causes you to backtrack) or you solve the puzzle or find out it's unsolvable (which ends the recursion). Instructions Part 0: Make a copy of your Sudoku #2 Solution We will be building off your Sudoku #2 solution. I recommend beginning this assignment by making a new folder with a copy of your Sudoku #2 solution…
In JAVA Recursive Array Search. Define and test a recursive method for a sequential search of an integer array. The method should return the index of the searchKey in the array, or return -1 if the searchKey is not found.

Write a recursive Java function displayOutIn that displays two items from an array list at one instance from out-to-in. until one or last two items displayed and the process stops. For example, given array A = {15, 74, 106, 10, 9, 86, 34} the displayOutIn function displays the following: 15, 34 74, 86 106, 9 10
python assignment Matrix class Implement a matrix class (in matrix.py). a) The initializer should take a list of lists as an argument, where each outer list is a row, and each value in an inner list is a value in the corresponding row. b) Implement the __str__ method to nicely format the string representation of the matrix: one line per row, two characters per number (%2d) and a space between numbers. For example: m = Matrix([[1,0,0],[0,1,0],[0,0,1]]) print(m)> 1 0 0> 0 1 0> 0 0 1 c) Implement a method scale(factor) that returns a new matrix where each value is multiplied by scale. For example: m = Matrix([[1,2,3],[4,5,6],[7,8,9]])n = m.scale(2)print(n)> 2 4 6> 8 10 12>14 16 18print(m)> 1 2 3> 4 5 6> 7 8 9 d) Implement a method transpose() that returns a new matrix that has been transposed. Transposing flips a matrix over its diagonal: it switches rows and columns. m = Matrix([[1,2,3],[4,5,6],[7,8,9]])print(m)> 1 2 3> 4 5 6> 7 8…
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.

Java Programming : A party has been organised on cruise. The party is organised for a limited time (T). The number of guests entering (E[i]) and leaving (L[i]) the party at every hour is represented as elements of the array. The task is to find the maximum number of guests present on the cruise at any given instance within T hours. Example 1: Input : 5 > Value of T [7,0,5,1,3] -> E[], Element of E[0] to E[N-1], where input each element is separated by new line [1,2,1,3,4] -> L[], Element of L[0] to L[N-1], while input each element is separate by new line. Output : 8 -> Maximum number of guests on cruise at an instance. Explanation: 1st hour: Entry 7 Exit: 1 No. of guests on ship : 6 2nd hour : Entry Exit : 2 No. of guests on ship: 6-2=4 Hour 3: Entry: 5 Exit: 1 No. of guests on ship : 4+5-1-8 Hour 4: Entry 1 Exit 3 No. of guests on ship: 8+1-3=6 Hour 5: Entry 3 Exit: 4 No. of guests on ship: 6+3-4-5 Hence, the maximum number of guests within 5 hours is 8.
