Programming Exercises

The purpose of this project is to be a collection of solutions to programming exercises. The solutions are split into directories based on language:

• C++
• MySQL
• Haskell

In particular, there are many C++ solutions to problems from Leet Code in the directory /cpp/.

The solutions are self-contained. They will compile to create executables for testing; this is despite the fact that Leet Code only requires one to implement individual class member functions.

Blog Entries

Some of the solutions to the exercises are discussed on my blog; here is a list of the solutions that are discussed as blog entries:

• C++ Solution for Leet Code 297: Serialize/Deserialize a Binary Tree.
