Generate random maze represented as 2D array of ones and zeros using depth-first search

maze-generator

Introduction

Generate a random maze represented as a 2D array of ones and zeros using depth-first search. Note that the "symbolic maze" generated is showing the actual path forged by the algorithm; if this were to be drawn as a true maze, the blank spaces and asterisks would be swapped so that blank spaces would represent the potential path and asterisks would represent walls.

Next steps

• Modify algorithm so that the path charted doesn't form awkward corners where asterisks are diagonal neighbors
• Pick arbirary maze start and finish
• Write complementary code to solve the generated mazes
• Generate three dimensional mazes
