Write a function that accepts a cell array of strings and returns another cell array of strings with only the duplicates retained.
Examples:
Input strs = {'a','b','a'}
Output dups is 'a' Input strs = {'a','b','c'}
Output dups is Empty cell array: 0-by-1
Why not just an isequal(correct,result) in the tests?
Consequently, a lot of solutions leave duplicates in the result.
How should higher multiplets be treated?
That's cheating :D
This doesn't need the first line of code at all ...
ah, i didn't realize that you could leave duplicates in the final result and still have it pass the test cases; nicely done
