A week ago I was trying to find some algorithm exercises and I found exercism.io, a website that helps you practice your developer skills using your terminal, your favorite IDE and TDD 🙂
Besides the TDD approach, what I really liked about it is that it encourages you to solve problems iteratively, one test at a time and when all tests are passing, refactor your code for a better solution.
It also lets you discuss each others solutions and I’ve already received some nice advices. Some exercises also made me learn some new methods that I’ve never used before like reduce/ tr and learn that count can receive a block!
I suggest you try it and then let me know if you liked it or not and if you did, comment here your profile so we can try to help you improve your coding skills 🙂
ps: you can also see my answers and help me improve mine
