Exploration of algorithms, recursion, recurrences, asymptotics, relations, graphs, and trees with practical implementations.

Recursion is a principle closely related to mathematical induction. In a recursive definition, an object is defined **in terms of itself**. We can recursively define sequences, functions and sets. > ...

If you are interested in the real-world applications of numbers, discrete mathematics may be the concentration for you. Because discrete mathematics is the language of computing, it complements the ...
