i had construct a maze which i could setup the n x n with user input successfully.The problem is i cannot correctly specify the visited area with 'R',which is a symbol of a robot.

}For example w is a part of direction to move upward of the 'R',in the maze.But the loop seems cannot remember the math operation on the ro variable to test whether it matching with rowend variable value.Anything i could done so the 'R' symbol could correctly place on the maze?
