There's not really a way of measuring it but I used some different proxies such as 1. https://projecteuler.net/ https://projecteuler.net/ Math-heavy but interesting 2. Clojure koans (http://www.4clojure.com/ http://www.4clojure.com/) Here you're good if your solutions are close to the best solution - which is often short and readable (= elegant?) There are probably similar koans for other languages and I'd also strongly recommend a functional language (because it frees yourself from the shackles of imperative and OO thinking, but YMMV)
