These are my solutions to various problems from https://projecteuler.net/.
Warning: the files in this repository contain complete solutions, which might spoil the fun of solving them yourself.
Most problems are written in C#, and share the common EulerDotNet
library. This library contains tools for number theory, combinatorics, infinite precision integers and parallelization (I'm quite proud of the latter).
Nowadays I mostly work in Python 3, and the EulerDotNet
library is no longer maintained.
