You must order your beer with egg in it.

JB>immangine the first array had {-1;-1;0;0}  in it.

JB>the second array gets {-1;0;0;0;}

True.  In thinking about that problem the only way (that I can see) to 
overcome it would be to dynamically create an array based on the size of 
the input data set OR do a linked list thing.
