Sorting arrays is simple, but I find it a little disappointing how easy the actual solution is… Access to Arrays.sort() was prohibited in prior tasks. I think it should be here too. ► All CodeHunt Episodes: http://goo.gl/WtTJ3L ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss an Episode: http://goo.gl/whzDi1 «CodeHunt» An educational […]

Task 9 was easy enough, but task 10 freaked me out, until I found that the generated test cases are simply wrong. My final solution does not fulfill all of them! What is it MSResearch? Wrong test cases or acceptance of a wrong solution? ► All CodeHunt Episodes: http://goo.gl/WtTJ3L ► […]

To refactor safely, we want to get test coverage up. Our ideal is always 100%, but remember that this doesn’t guarantee a good test suite. Use the coverage as a guide to missing test cases, but don’t forget to think about cases that might not be revealed by coverage! ► […]

This is a tough one. Took me a while to wrap my head around the concept. Stumbled across the solution more by chance than by systematic search, but I got it right, in the end 😉 ► All CodeHunt Episodes: http://goo.gl/WtTJ3L ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss an Episode: […]
