Sometimes i'm not exactly sure how Project Euler grades their problems, this problem is very similar to Problem 518, which is a 20% problem, and this problem has smaller constraints so it actually ended up being easier The number $512$ is interesting because it is equal to the sum of its digits raised to some power: $5 + 1 + 2 = 8$, and $8^3 = 512$. Bluntly put: If the algorithm can't solve it in under a minute, it sucks, and is therefore not a good solution. April, June and November. The answer is 171 but my code gives 1199 which is way off the expected answer. 15% Difficulty. 35% Difficulty. com/watch?v=FiHSPt_cBV0-~-~~-~~~-~~-~- You are given the following information, but you may prefer to do some research for yourself.
