I recently stumbled across CodeCrafters again1. In a nutshell, they give a number of ‘Build Your Own…’ courses, each of which will automatically create a repo for you, guide you through solving the program step by step, and provide some feedback on the way.
On one hand, it’s a freemium (one problem a month is free) / paid service. I wish they had tiers. I really think their monthly fee is a bit steep for what they offer (we’ll come back to that). But on the other hand, it’s a neat tool and I’ve been wanting some more larger programming projects to learn more Rust on, so away we go!
First up, grep!
