/// This is my first Project Euler problem I attempt to solve in Dart.
/// It has been quite a few years since I solved the last problem and 
/// I did not even know about Dart when I did it. 
/// I think that Dart is not best suited for these kinds of problems because it is not performant 
/// and also object-oriented instead of functional (which I would suppose works better for math problems) 
/// or maybe Python because the syntax is better to solve math problems, but I have solved these problems in 
/// Go, Kotlin, JavaScript, and other similar languages in the past and thus I see this as an opportunity to learn even more about Dart :)
