g In any language of your choice (java? c++? anything you like), write a B-Tree implementation (or B+Tree). Your code will need to create and store data in a file. Your code should be command line based (command line arguments would have value, and filename), with a command to insert an entry into the tree, and another command to look it up. Also support range lookup.

Scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below. what experimental evidence led to the development of this atomic model from the one before it? a few of the positive particles aimed at a gold foil seemed to bounce back. the colors of light emitted from heated atoms had very specific energies. experiments with water vapor showed that elements combine in specific proportions. cathode rays were bent in the same way whenever a magnet was brought near them.
