Please dont copy from chegg it is wrong, do your own work JAVA Project 18.20 (Maze Traversal Using Recursive Backtracking) The grid of #s and dots (.) in Fig. 18.23 is a two-dimensional array representation of a maze. The #s represent the walls of the maze, and the dots represent locations in the possible paths through the maze. A move can be made only to a location in the array that contains a dot. Write the recursive method (mazeTraversal) to walk through mazes like the one in Fig. 18.23. The method should receive as arguments a 12-by-12 character array representing the maze and the current location in the maze (the first time this method is called, the current location should be the entry point of the maze). As mazeTraversal attempts to locate the exit, it should place the character x in each square in the path. There's a simple algorithm for walking through a maze that guarantees finding the exit (assuming there's an exit). If there's no exit, you'll arrive at the starting location…
6.9 LAB: All permutations of names   Write a program that lists all ways people can line up for a photo (all permutations of a list of Strings). The program will read a list of one word names (until -1), and use a recursive method to create and output all possible orderings of those names, one ordering per line. When the input is: Julia Lucas Mia -1 then the output is (must match the below ordering): Julia Lucas Mia Julia Mia Lucas Lucas Julia Mia Lucas Mia Julia Mia Julia Lucas Mia Lucas Julia   import java.util.Scanner;import java.util.ArrayList; public class PhotoLineups { // TODO: Write method to create and output all permutations of the list of names.public static void allPermutations(ArrayList<String> permList, ArrayList<String> nameList) {} public static void main(String[] args) {Scanner scnr = new Scanner(System.in);ArrayList<String> nameList = new ArrayList<String>();ArrayList<String> permList = new ArrayList<String>();String name;//…
1001 UnaI (p E. Write a program named as ProblemE_.cpp that constructs a BST from a given postorder traversal of that tree. For example, if the given traversal is {1, 7, 5, 50, 40, 10}, then the output should be the tree shown in Problem 3. Hints: • Write a recursive function to do the followings: a) Get the last element of the array and make it root of the BST. b) Find the index i such that the value in i-1 is the first value smaller than the root. c) Recursively call a function to do the same for left subarray (1 .. i-1) and right subarray (i..size-2). i) Get the last element of right half and make it right child of the root created in step a. ii) Get the last element of left half and make it left child of the root created in step a. d) return root.
