    Question need some help on this problem - a few hints please

    i was given d this prob. as a proj.Pls give some hint how to get about it : -
    there is a 3D maze(n*n*n;n is odd).there are some hindrances(1)to be avoided. the starting position is to be chosen and d objective is to reach the centre of the maze. if it is not possible to reach then print "NO" else print "YES" and find the shortest path.
    eg.
    ----------------
    1 0(start) 0
    0 1 0
    1 1 1
    --------------------
    1 0 1
    1 0(destn) 0
    0 1 0
    --------------------
    0 0 0
    1 1 0
    1 0 0
    --------------------
    output: Yes,3

    Make a google search for the A* (A-star) algorithm. It can find the optimal path through a labyrinth assuming one exists.

    As a sidenote, I implemented A* in a program. It can be found here:

    That program uses a 2D maze, but I don't think it's hard to extend to 3D.
