This is the practice competition for the 2019 Code Kerfuffle.

These questions are similar to the questions we will use for the real competition. These cover a wide range of algorithm and data structure topics. Most questions have a naive solution, but can be solved more efficiently. The more efficient solution will be neccessary to pass all the test cases.

Hints

• Pick your most productive language, not the "fastest". (ie Python is usually a better choice than C)
• All questions are worth the same amount of points, so solve the easiest questions first.
• Run the sample test cases first by clicking 'Run Code'.
