What is this website?

This website is one of the largest collections of explained Project Euler Solutions, not just code, but detailed explanations of the mathematics and coding I used to solve over 300 problems, with as many interactive tests as possible, to help anyone in need in their Project Euler journey! 

Furthermore, this website is also, largely, my personal journey of coding. I learned to code mainly through these problems and hence you may find some solutions which are severely not optimized, or even take the time to explain the most basic of programming or math concepts, but that was because when I solved the problems those concepts were not basic to me! 

Why am I doing this?

To begin, websites such as https://euler.stephan-brumme.com/ and https://www.nayuki.io/ inspired me, and I thought it would be an interesting project for myself as only when you can explain something to someone else, do you truly understand it.

Stephan Brumme encapsulates beautifully why anyone would do such a project (See here) and I am doing it for the same reason. Many times before I have been stuck on a problem not knowing how to progress, or believing that I am doing everything correctly but just can't get the answer and this is the time to seek help.

At the end of the day Project Euler is a tool to increase your knowledge of mathematics and programming and if you are unable to progress after trying your best (Which you should most definitely do before seeking help), you may have gained some tenacity but you may not even know where you went wrong, or how you could improve; however, if you can be guided along the correct path you can gain a tremendous amount of knowledge and maybe next time you see a similar type problem (which may be much harder) you can now solve it and apply the knowledge you learnt. 

Of course this can only happen if you take the time to fully understand what it is another person is saying, and it is for this reason I will aim to provide detailed explanation's (but may omit steps that you can prove on your own if you're really trying and not just copying) on how I solved the problems. In addition, I want to make as many of my solutions interactive as possible as I have always found extra test cases to be very useful as hints. 

I will explain my algorithms and of course as much mathematics as I can behind the problems as this is more my specialty, and hopefully by the time you're done reading you can understand how to solve the problem you were stuck on!

End goal?

My goal is to learn, become a better programmer and a better mathematician. The goal for this website is to become the largest source of detailed explanations for Project Euler available! 

About me

I'm currently a PhD Student at Nanyang Technological University Singapore, my favourite topic is Algebraic Number theory and I'm working on the Equiangular line problem in Complex Spaces, but I also love programming, and of course, this led me to Project Euler which is an absolutely brilliant website that gives tons of beautiful mathematical and computational problems!
