Hi,
    In this week, we worked on in-memory structures:- Which representation to choose(prefix or expression tree), How to store values and how authentication will be done.

   I have prepared pseudocode to implement this subtask and have made implemented some part of code. Hopefully by 25th May, I will finish off with >50% of the project.

   I will declare Phase-2 deliverables next Monday(26 May).

Kind regards,
Ankit Kumar
