The lists do not have 'names' or summary. They have just elements. So elements display is essential. My idea is to find the list where I can add a 'new element'. I can use Hash for each list. It would be nice if display order for mini-lists is 'in the order of insertion in the original lists', but not absolutely necessary.

I concur that it is a lot of work. Assuming I have L lists, each list has an average of N element and I like to display top T elements, what would be the order of algorithm I should be expecting?
