Interviews

Code related to technical interview questions

Each package corresponds to the underlying data structure or problem of a technical interview question.

Disclaimer

All the code is my answer to the question and it should not be taken as granted. Technical interviews are about discussion and refinements of a first brute force yet well-implemented solution. There may be some better way to implement the solution(s).

Highlights

• Range Minimum Query (using a sparse table)
• Left-leaning Red-Black Tree
• Max, Power, Sum
• Union-Find (with path compression)
• Shellsort
• Pattern matching (Knuth-Morris-Pratt algorithm)

Misc

Take a look at the tests to get a better idea on how to use the methods. I tried to comment whenever there were some tricks involved.
