The Maze

Explore how to solve the maze puzzle by applying depth-first search algorithms with recursion in Kotlin. Understand moving through the maze, handling walls, and reaching a destination. This lesson helps you tackle similar pathfinding problems efficiently, preparing you for coding interviews.

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.

Constraints

  • maze[i][j] must be 0 or 1, initially.
  • mazeLength == maze.length
  • mazeSubarrayLength == maze[i].length
  • 1 <= mazeLength, mazeSubarrayLength <= 100
  • start.length, end.length == 2
  • 0 <= startrowstart_{row}, endrowend_{row}
