You are given an array of arrays a. Your task is to group the arrays a[i] by their mean values, so that arrays with equal mean values are in the same group, and arrays with different mean values are in different groups. Each group should contain a set of indices (i, j, etc), such that the corresponding arrays (a[i], a[j], etc) all have the same mean. Return the set of groups as an array of arrays, where the indices within each group are sorted in ascending order, and the groups are sorted in ascending order of their minimum element.

The assignment was just right difficult. I think with it I could properly show my main knowledge of programming the Android apps. It took me about 15 hours of work, which is a bit more than they assumed, but it was my fault I needed more time than it was planned. There was no deadline. I just needed to let them know the estimated date, when I was planning to finish it, but they said I can extend the submission deadline if I'd need. The technical interview was nicely structured by topics (eg. architecture of project, handling data, frameworks etc.). I liked if I didn't know or understand something I got full explanation. Also I got full feedback about my assignment so I know what I did by their expectations or if not, what I could do better or differently.
