c# IV - Eikon pre-screening

This is a 1) Knowledge based and 2) algo-based IV. The areas covered are evergreen and stable.

TCP vs UDP
ArrayList vs List
Mutex vs Semaphore -- see other blog

Q: lock vs Mutex
%%A: any reference type object can be a lock...

Q3a: implement a data structure with random access and fast add/remove on both ends.
%%A: deque, using sements linked by a directory, as in STL
A: now I know circular array is simpler.

Q3b: How about the directory data structure in your deque
%%A: perhaps a hashtable?
A: Now I know it's a vector of pointers

Q: 2 servers to synch their clocks on startup. No need for correct time, just the same time.
%%A: Side B will query A (or receive broadcasts) and update itslef. Side A will blindly broadcast. Both query and broadcast are
simple TCP operations.
