Create A Similar Coding Program Using C++ Like the Example Below, Remember to use C++ Only, And Remember to use Good Commenting Programming Practices like the example given Below.

Example:

/* C++ program to solve Rat in a Maze problem using backtracking */ #include

// Maze size #define N 4

bool solveMazeUtil( int maze[N][N], int x, int y, int sol[N][N]);

/* A utility function to print solution matrix sol[N][N] */ void printSolution(int sol[N][N]) { for (int i = 0; i < N; i++) { for (int j = 0; j < N; j++) printf(" %d ", sol[i][j]); printf(" "); } }

/* A utility function to check if x, y is valid index for N*N maze */ bool isSafe(int maze[N][N], int x, int y) { // if (x, y outside maze) return false if ( x >= 0 && x < N && y >= 0 && y < N && maze[x][y] == 1) return true;

return false; }

/* This function solves the Maze problem using Backtracking. It mainly uses solveMazeUtil() to solve the problem. It returns false if no path is possible, otherwise return true and prints the path in the form of 1s. Please note that there may be more than one solutions, this function prints one of the feasible solutions.*/ bool solveMaze(int maze[N][N]) { int sol[N][N] = { { 0, 0, 0, 0 }, { 0, 0, 0, 0 }, { 0, 0, 0, 0 }, { 0, 0, 0, 0 } };

if (solveMazeUtil( maze, 0, 0, sol) == false) { printf("Solution doesn't exist"); return false; }

printSolution(sol); return true; }

/* A recursive utility function to solve Maze problem */ bool solveMazeUtil( int maze[N][N], int x, int y, int sol[N][N]) { // if (x, y is goal) return true if ( x == N - 1 && y == N - 1 && maze[x][y] == 1) { sol[x][y] = 1; return true; }

// Check if maze[x][y] is valid if (isSafe(maze, x, y) == true) { // Check if the current block is already part of solution path. if (sol[x][y] == 1) return false; // mark x, y as part of solution path sol[x][y] = 1;

/* Move forward in x direction */ if (solveMazeUtil( maze, x + 1, y, sol) == true) return true;

/* If moving in x direction doesn't give solution then Move down in y direction */ if (solveMazeUtil( maze, x, y + 1, sol) == true) return true; /* If none of the above movements work then BACKTRACK: unmark x, y as part of solution path */ sol[x][y] = 0; return false; }

return false; }

// driver program to test above function int main() { int maze[N][N] = { { 1, 0, 0, 0 }, { 1, 1, 0, 1 }, { 0, 1, 0, 0 }, { 1, 1, 1, 1 } };

solveMaze(maze); return 0; }

This is an Example only to give you an Idea on What to do.
