Project Euler Level 11 BadgeI managed to reach Level 11 (275-299 problems solved out of over 840 at the moment). To put this in perspective, there are 33 levels. However even Level 11 has less than 250 members at the moment (2023) and levels 12 through 33 have about 1,100.
The problems are very challenging, and I admire how clever some people’s solutions are (you can browse what others post as solutions after you submit a correct answer yourself).
It’s a great learning experience if you want to learn how to push coding to the limit and tackle problems involving huge numbers. Brute force approaches seldom work, so you need to think about the mathematics involved as well.
