UniqueLab 2018 Spring Assignment 1, Part 2

Implement set in C++ STL.

You are expected to implement:

• insert(const T&)
• erase(const T&)
• clear()
• count(const T&) // return 1 if element exists, 0 otherwise
• empty()
• size()

Please refer to STL documents for details.

Since time is short, you needn't implement features of templates or iterators. Just let T = double and change return values of most functions to void instead.

However, you must use LLRB as internal data structure for this assignment. Any other balanced BSTs are not acceptable.
