Spoiler-free review of #ProjectEuler problem 757 (Stealthy Numbers): this is a nice little problem with a nice solution. It made me feel quite stupid because it took me a while to solve it despite its difficulty rating of 3/39. I don't really understand these difficulty ratings. I know they are computed from the solve statistics, so they are "objective", but I just cannot see how 349 is an 11/39 if 757 is a 3/39. Recommended: https://projecteuler.net/problem=757
