rat maze Algorithm
The series consists of The Maze Runner (2009), The Scorch Trials (2010) and The death Cure (2011), as well as two prequel novels, The kill Order (2012) and The Fever code (2016), and a companion book titled The Maze Runner file (2013).The series, revealing details in non-chronological order, says how the universe was devastated by a series of massive solar flares and coronal mass ejections. The Maze Runner is a series of young adult dystopian science fiction novels write by American writer James Dashner.
/*
A Maze is given as N*N binary matrix of blocks where source block is the upper
left most block i.e., maze[0][0] and destination block is lower rightmost
block i.e., maze[N-1][N-1]. A rat starts from source and has to reach destination.
The rat can move only in two directions: forward and down. In the maze matrix,
0 means the block is dead end and 1 means the block can be used in the path
from source to destination.
