Hi,
Thank you for the detailed response. I have done the required reading and
have documented my understanding of the various aspects of the project in
the following document :
https://docs.google.com/document/d/1rGqABpdIOaIcIUCID9nsz3neMwPmbMoyhvaGwT0gjvM/edit?usp=sharing
I have answered the two specific questions under the "Suggestions" heading
of the document. I have also worked out two examples explicitly as
suggested. I have a couple of doubts regarding the project which I have
mentioned under the "Doubts" heading in the above document. I would be
obliged if anyone could help clear those doubts or provide a direction
towards a better understanding of those issues. Please feel free to comment
if you have any suggestion with respect to any part of the document.
Thanking you,
Aditya Jain
