Exploring Project Euler 20
Welcome to our comprehensive guide on Project Euler 20.
- Problem
- In this one we are basically just combining a few basic concepts we have already covered previously so this one is really quick.
- In this video I tackle a problem about cyclic sets of figurate numbers. Have you ever heard of a heptagonal number?
- In this video we use graph theory and knowledge of a famous NP-complete problem to tackle the first problem from

In-Depth Information on Project Euler 20
Adding up all the digits in 100! (factorial, not yelling the number). Videos going forward should be in 1440p 60fps if all goes right. I use the Big Integer class from the last two videos to solve In this video we solve the Factorial Digit Sum. Please Subscribe! Leave comments and questions in the comment section below.

In summary, understanding Project Euler 20 gives us a better perspective.
