Watching course of gamification, I reminded one interesting source — Project Euler.
- Why is this source interesting?
It's just a problemset that contains math and algorithm problems, but they have just one test. Maybe, it's a bit puzzle , so I'll explain on an example:
What is the 10 001st prime number?
Obviously, there is only one answer and one test — and that's all you need to get AC.
This source contains nearly 420 problems
During solving problems,you'll get different achievements, which will motivate you — they have cool design). E.g. they have Fibonacci Fever achievement — for solving 12 problems numbered by Fibonacci numbers.
P.S. First time I met this project two years ago — — I got 20 percent of my mark in one of subjects for solving this problems) I haven't found any posts about this project, so I wrote one.
