If the input is not in key order, why did you show your sample data to be in key order?
What order do you want the output to be in? Do you have a preference for which 'a1' is retained for a particular key, given that they may be scattered across your input?
There are loads of examples here (and elsewhere). It is not rocket surgery once you have the outline. Of course, you've just changed the outline.
