**Requirements - File Change Detector Project**
Attached are 2 methods we need assistance in writing. Note we are using VB .NET. However, it's not a requirement that the inner logic for these methods be written in a .NET language. For example, for performance reasons you may want to use C or unmanaged C++. Regardless of language, please make sure:
-The logic can easily be called from .NET and will accept/return .NET friendly datatypes
-Performance is important but so is size ??" the size of the byte array returned by the ExtractFileChanges method should be as small as possible. If it isn’t small, it will negate the benefits of extracting the changes (i.e. we might as well store the UpdatedFile in its entirety).
-While the format of the returned Byte array is not important, do make sure you document the format and comment your code accordingly.
Methods to be implemented (more details in attachment):
PublicFunction ExtractFileChanges(ByVal OriginalFile As Byte(), ByVal UpdatedFile As Byte()) As Byte()
End Function
Public Function ReconstructFile(ByVal OriginalFile As Byte(), ByVal FileChanges As Byte()()) As Byte()
End Function
## Deliverables
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
2) Deliverables must be in ready-to-run condition, as follows:
-demonstration of these methods successfully implemented (in a simple Windows app) against both text and binary files.
3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).
