More_efficient_newton_forward_interpolation.py

Updated code keeps on updating the values in y list rather than storing all values of difference table at the same time. So it takes less space. Also, as difference is being calculated, required answer is also being calculated at the same time, so it takes less time. Updated code is also taking care of the cases in which Newton Forward Interpolation cannot be used.
