My colleague and I have dispute. We are writing a .NET application that processes massive amounts of data. It receives data elements, groups subsets of them into blocks according to some criterion and processes those blocks. Let's say we have data items of type Foo arriving some source (from the network, for example) one by one. We wish to gather subsets of related objects of type Foo, construct an object of type Bar from each such subset and process objects...

This assignment attempts to model the social phenomenon twitter.
It involves two main classes: Tweet and TweetManager. You will load
a set of tweets from a local file into a List collection. You will
perform some simple queries on this collection.
The Tweet and the TweetManager classes must be in separate files
and must not be in the Program.cs file.
The Tweet Class
The Tweet class consist of nine members that include two static
ones (the members decorated with the...
