I learnt three big things from struggling with test #5 in Java:
1. StringBuilder, don't underestimate how important it is when working with Strings;
2. IO is slow, minimise where possible; and
3. Really think about the the aspects that contribute the most to overhead/performance and not try small things which take a lot of time and result in small/negilible gains.

Thank you for this challenge!
