What's new: free DSA practice on Nokku.ai. 8 lessons explain each data structure with a picture you know (a stack is a pile of plates), then 24 problems you solve in your browser in Python or JavaScript, with step-by-step hints and a weekly leaderboard. Who it's for: anyone preparing for coding interviews who finds DSA intimidating. Why it matters: memorised solutions fade fast. Starting from a picture makes ideas stick, and it's free, with no account needed to start.
