Chapter 7, Problem 7.22E
(Maze Traversal) The following grid is a two-dimensional array representation of a maze.
The # symbols represent the walls of the maze, and the periods (.) represent squares in the possible paths through the maze.
There’s a simple
Write recursive function mazeTraverse to walk through the maze. The function should receive as arguments a 12-by-12 character array representing the maze and the starting location of the maze. As mazeTraverse attempts to locate the exit from the maze, it should place the character x in each square in the path. The function should display the maze after each move so the user can watch as the maze is solved.

Method Details:
public static void rotate(int[] array, boolean leftRotation, int positions)
Rotates the provided array left if leftRotation is true; right otherwise. The number of positions to rotate is determined by positions. For example, rotating the array 10, 20, 7, 8 two positions to the left will update the array to 7, 8, 10, 20. Only arrays with 2 or more elements will be rotated. Hint: adding private methods that rotate an array one position to the left and one position to the right can help.
Parameters:
array -
leftRotation -
positions -
Throws:java.lang.IllegalArgumentException - When a null array parameter is provided
Rotate Right k cells (use python)
Consider an array named source. Write a method/function named rotateRight( source, k) that rotates all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly.
Example:
source=[10,20,30,40,50,60]
rotateRight(source,3)
After calling rotateRight(source,3), printing the array should give the output as:
[ 40, 50, 60, 10, 20, 30]
Determine whether the following array declarations are valid. If a declaration is valid, write VALID. If it is invalid, you can make assumptions and write a correct declaration.

- Indicate true or false for the following statements: Every element in an array has the same type. The array size is fixed after it is declared. The array size declarator must be a constant expression. The array elements are initialized when an array is declared.arrow_forward(FYI: Pseudocode is required (Not any programming language) Design a pseudocode program that loads an array with the following 7 values. Add one more word (of your own choosing) for a total of 8 words. biffcomelyfezmottleperukebedraggledquisling Be sure to use lowercase, as shown above. This will make the processing easier. Ask the user to enter a word Search through this array until you find a match with the word the user entered. Once you find a match, output "Yes, that word is in the dictionary". If you get to the end of the array and do NOT find a match, output "No, that word is not in the dictionary". The program should work with any set of words in the arrays. If I were to change the words in the arrays, it should still work. If you need help, look at the search example in your textbook.arrow_forwardInstead of utilizing an array, would it be beneficial to work with vectors instead?arrow_forward
- (Two dice are rolled 100 times (you can do this with two random values from 1 to 6 in your program). After rounding 100 times, keep the iteration value of how many times each state occurs in a two-dimensional array. For example, the index number of [1,1] must follow the number of times the dice rolls 1 to 1).arrow_forwardThis does not appear to be the answer to this question; Cheese's position is randomly generated in a 5x5 grid. The initial positions are x,y. The position of Cheese is not specified as (3, 4)arrow_forwardProblem 4: Magic Square Test A magic square of order n is an arrangement of n × n numbers, usually distinct integers, in a square, such that the n numbers in all rows, all columns, and both diagonals sum to the same constant. See all rows’, columns’ and diagonal’s sum is same. Write a main method where first you need to input n. Then input n*n integers and form a 2D matrix. Print “YES” if the matrix is magic square and print “NO” Otherwise. Sample input: 3 2 7 6 9 5 1 4 3 8 Output: YESarrow_forward
- Write application that prints matrix with rows and columns, number of rows and columns are input parameters (Have main method) Use DART programming languagearrow_forwardProblem 1: Complete the sumOfDiagonals method in SumOfDiagonals.java to do the following: The method takes a 2D String array x as a parameter and returns no value. The method should calculate and print the sum of the elements on the major diagonal of the array x. In order to have a major diagonal, the array passed into the method should be a square (n-by-n), if it's not a square your program should handle that situation by throwing an exception. (Do Not worry about ragged arrays) If the array is a square, but there is a non-integer value on the major diagonal, your program should handle that situation by throwing an exception. When handling the exceptions, be as specific as you can be, (i.e. Do Not just use the Exception class to handle all exceptions in one catch block). Make the proper calls to the sumOfDiagonals method from the main method to test your sumOfDiagonals method on all the String arrays provided in the main method.arrow_forwardCreate a program for Matrix with the following requirements: 1. Allow the user to select what operation to perform like: finding eigenvalues and eigenvectors, sketching the Gershgorin circles, and diagonalization. 2. Allow the user to input any size of the matrices and their elements. 3. Display the matrix input and the result of the operation.arrow_forward
- (Average the major diagonal in a matrix) Write a method that averages all the numbers in the major diagonal in an n * n matrix of double values using the following header: public static double averageMajorDiagonal(double[][] m) Write a test program that reads a 4-by-4 matrix and displays the average of all its elements on the major diagonal.arrow_forwardCorrect answer will be upvoted else Multiple Downvoted. Computer science. assume mid=⌊max(array)+min(array)2⌋, where max and min — are capacities that track down the maximum and the base array components. At the end of the day, mid is the amount of the maximum and the base component of array separated by 2 adjusted down. Then, at that point, the array is parted into two parts left and right. The left array contains all components which are not exactly or equal mid, and the right array contains all components which are greater than mid. Components in left and right maintain their relative control from array. During the third step we pick which of the left and right arrays we want to keep. The picked array replaces the current one and the other is permanently discarded. You want to assist Mike with discovering the aftereffects of q beauty tests. Note that you test the attractiveness of the array a, so you start each beauty test with the primordial (initial) array a.…arrow_forwardState whether the statement are true or false. If the answer is false, explain why? " If there are fewer initializers in an initializer list than the number of elements in the array , the remaining elements are initialized to the last value in the initializer list.arrow_forward
