Lol. Ok you can use your own quick sort, but what the reason, if the task is not implement your own quick sort?

System.out.println(peopleInLine);

is there a way to see all the test suite? I can figure out what's wrong with my code if i don't know what array is introduced as parameter

yes

just me.....Reinventing the wheel :))

oh yes, you'r right, i was thinking at the bigest not the next bigger :)

Because the next bigger is, I would say, 2107?

For the number 2071 why is incorrect the output: 7210?

this kata is to easy for 5 kyu

What happens if there are more than 3 of a digit?...

I noticed that the majority use LINQ so they can post a solution with 2 or 3 lines of code...that's good, but is this what is all about? not using your brain for creating functions, just using others methods. It's like someone tells you to find a solution to sort an array and you just write "array.sort()"...you know what i mean. Great site by the way :)
