The problems in this repository are extracted from "Programming Interviews Exposed: Secrets to Landing Your Next Job" by Mongan et al. The folder problems also includes some miscellaneous problems that I add when I find them or hear about them.

Solutions were implemented by myself in Python and by Stefan Achleitner in Java. The chapters covered are the following:

• Chapter 5: Trees and Graphs
• Chapter 6: Arrays and Strings
• Chapter 7: Recursion
• Chapter 8: Sorting
• Chapter 13: Graphics and Bits Manipulation

I encourage you to open issues if you find bugs or possible improvements (time or space complexity) in my solutions. Similarly, if you have additional problems and/or solution source code that you would like to share with others, feel free to submit a pull request.

Good luck for your interview preparation!
