This repository mainly consists of the solutions that I have submitted to several online judges. Feel free to take a look at my approach to these problems.

If you have any questions about my approach to them, suggestions or just want to discuss any particular problem, you can contact me at delvaldavid1@gmail.com.

There is also a pdf (Implementations/implementations.pdf) with explanations and example code for some of the algorithms that I have learnt. As of the last time I edited this:
