Project Euler 20 - Detailed Analysis & Overview

In this video, I will be coding the solution for the problem # 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 n! means n x (n-1) x ... x 3 x 2 x 1. For example, 10! = 10 x 9 x ... x 3 x 2 x 1 = 3628800, and the sum of the digits in the number 10! I mean BigInt just melts this one. It's perhaps against the spirit of Want my help with your code? Check out the options here:
