Hi Sitha, To answer this properly, we require an understanding of a couple of things. 1. How do you define "duplicates"? I assume that you mean, for a given column, duplicates are a data item that is repeated more than once. For example: 2 3 r s 8 1 a 2 d u 8 4 1 h w w u a 4 1 9 In the first, third, and sixth columns, respectively, '2', 'u', and '1' are duplicates. Or do you, perhaps, mean something else entirely? 2. What is done when the data is eliminated? Do elements get undefined or shifted, perhaps? For example, in the diagram above, replacing the duplicates with spaces gives us: 3 r s 8 a d 8 4 h w w a 4 9 Is that what you are looking for, or do things get shifted left or up, or some combination of that?
