Robot position finder

Finds the poistion of a robot on a chess board.A common robotic problem

Suppose there is robot on a chess board whose cells are colored randomly, it will flag you whenever its left sensor reads red and right sensor reads blue. This Function return you all the possible positions of the robot.

This function deals with a real time robotic problem. The function takes parameters; board, which is the chess board , its dimensions, and color to be sensed at left and the coor to be sensed at right (I wrote red and blue just for explanation.)
