Now, come September, they’re ubiquitous.įarmers have to consider many factors to successfully make a corn maze, such as whether they have the right soil and climate, and how much time they want to devote to marketing and customer service. The history of the modern American corn maze - with its intricate aerial designs and winding trails - allegedly dates back to 1993, when Don Frantz and Adrian Fisher grew “The Amazing Maize Maze,” shaped like a stegosaurus called “Cornelius the Cobosaurus.”Īt the time, the three-acre corn maze in eastern Pennsylvania seemed like a veritable vanguard in a world of easy-to-solve geometric hedge mazes. This fall, though, I decided to challenge myself.Ĭorn mazes, otherwise (punnily) known as maize mazes, are a fall tradition - perhaps ironically, as corn crops are at their lushest in August. I am embarrassingly bad at reading maps (it’s not my fault my brain is broken). Corn mazes generally don’t rank very high on my list of autumnal to-dos. To make sure that the path is simple and doesn’t contain any cycles, keep track of cells involved in the current path in a matrix, and before exploring any cell, ignore the cell if it is already covered in the current path.Here are my favorite fall activities: shopping for kitschy sweaters at the thrift store, crafting punny Halloween costumes and experimenting with every type of squash at the farmers market. If a path doesn’t reach the destination or explored all possible routes from the current cell, backtrack. Then update the minimum path length whenever the destination cell is reached. The idea is to start from the given source cell in the matrix and explore all four paths possible and recursively check if they will lead to the destination or not. We can easily achieve this with the help of backtracking. To find the maze’s shortest path, search for all possible paths in the maze from the starting position to the goal position until all possibilities are exhausted. If source = (0, 0) and destination = (7, 5), the shortest path from source to destination has length 12. The path can only be constructed out of cells having value 1, and at any moment, we can only move one step in one of the four directions.įor example, consider the following binary matrix. Given a maze in the form of a binary rectangular matrix, find the shortest path’s length in the maze from a given source to a given destination.
