Question

The purpose of this assignment is to practice using Recursion with backtracking to solve a maze.

I need help to implement the private static void solve(Maze maze, Coordinate currentPos, ArrayList<Coordinate> path, ArrayList<Coordinate> history) method in the MazeSolver class.

```java /** * The recursive helper method that YOU will implement. This method will do all the work for * solving the maze. * * @param maze The {@code Maze} object to solve. * @param currentPos The {@code Coordinate} object that keeps track of your current position in the maze. * @param path The {@code ArrayList} of {@code Coordinate} objects that are currently on the path * from the start of the maze to the end. This ArrayList should only contain the * coordinates from start up to your current position, and eventually should contain * all the coordinates from start to end. * @param history The {@code ArrayList} of {@code Coordinate} objects that you have already visited. * This helps you to keep track of where you have been so you do not check the same * position more than once. */ private static void solve(Maze maze, Coordinate currentPos, ArrayList<Coordinate> path, ArrayList<Coordinate> history) { //THIS IS THE METHOD THAT YOU MUST IMPLEMENT. //YOU MAY NOT CHANGE THE METHOD HEADER } /** * Private method to print the final results once a solution has been found. * * @param maze A {@code Maze} object that we wish to display. * @param path An ArrayList of {@code Coordinate} objects that are on the path from the start * of the maze to the end. */ private static void printResult(Maze maze, ArrayList<Coordinate> path) { for (int i = 0; i < maze.getNumRows(); i++) { for (int j = 0; j < maze.getNumCols(); j++) { Coordinate current = new Coordinate(i, j); if (current.equals(maze.getStart())) { System.out.print("S"); ``` ### Explanation: This Java code represents part of a program to solve a maze using a recursive method. The code defines two methods: 1. **`solve` Method**: - Designed as a recursive helper that is meant to be implemented to solve a given maze. - **Parameters**: - `maze`: The maze object to solve. - `currentPos`: Keeps track of the current position within the maze. - `path`: An `ArrayList` that tracks the path from the start of the maze to the end
