Project Demo

First watch Maya run her finished version of her Maze Runner, to better understand what we are trying to create in this project. We've covered the solution code in the demo, so that you can challenge yourself first.

Maya's Demo:

Instructions:

Ask the user for a width, a height, and a simple maze with those dimensions. The maze will be represented as a grid of characters, where * represents walls, is open space, I is the start of the maze, and O is the end!

Here are some example inputs and their respective solutions:
