The Maze
Explore how to solve the maze puzzle by applying depth-first search algorithms. Understand how to navigate a 2D grid maze by rolling a ball through empty spaces until hitting walls, and how to track visited cells recursively. This lesson teaches you to map real-world pathfinding challenges to efficient coding interview solutions.
We'll cover the following...
Description
The maze is a puzzle game where the ball moves in the available empty spaces. The player aims to get the ball to the specified destination. The ball can go through the empty spaces by rolling up, down, left, or right, but it will not stop rolling until it hits a wall or reaches the destination and then hits a wall or reaches the end of a grid. After hitting a wall, the ball will choose the next direction before moving forward. The borders of the maze are considered walls.
