Recently, a friend was interviewed for a position in a technical company and received 4 programming tasks.
One of the tasks was to implement a binary search tree class using the Linked List implementation, by searching, adding and removing methods that could be accessed in a thread-safe manner. He had Visual Studio 2010, but no internet connection and about 30 minutes.
I would like people here to try to solve the problem without an internet connection in 30 minutes in C # (it is impossible to protect the police that I know, but I hope that you will be honest ...)
