My girlfriend is a great programmer, she loves to study Complexity of Algorithms, Number Theory, Computational Geometry, Graphs, Dynamic Programming... But she hates sharing her codes. One day she showed me a program that, given a numerical sequence, showed a value in the output. I used my social engineering skills and managed to steal this executable, but I do not know how it works. Can you reimplement this algorithm?
