Get better at programming through fun, rewarding coding exercises that test your understanding of concepts with Exercism.
Given a string of digits, output all the contiguous substrings of length `n` in that string.
Convert a binary number, represented as a string (e.g. '101010'), to its decimal equivalent using first principles.
Given an age in seconds, calculate how old someone is in terms of a given planet's solar years.
Every language has its own way of doing things. LFE is no different. Our mentors will help you learn to think like a LFE developer and how to write idiomatic code in LFE. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in LFE - they'll help you discover the things you don't know that you don't know.
