Your comment just made me realise why I hate any hackerrank &quot;challenges&quot; I have looked at. (Skyscanner uses them for interview tests, I have been close to applying twice, but got offered other jobs before I got around to completing them).<p>I have decided to try a warm up exercises a couple of times before applying but the way they word the questions is so unmeaningful: &#x27;n&#x27; lines with y variables, plus spending 20 minutes trying to work out how to read their input. No debugger and not easy way to cut and paste, as its all in a web form.<p>Fuck that, I am a software engineer, I usually read data from databases and name my variables properly and use tools to help me understand the problem, not hinder myself.
