Just tested this and it works for me. May be you passed the data as 
multiple parameters instead of one. I mean sth like

   answer getMissingNumbers(3,4,5,6,6,7,8,9,10,12,13,13,14)

instead of

   answer getMissingNumbers("3,4,5,6,6,7,8,9,10,12,13,13,14")

This algorithm makes no assumption on the order of data except that 
it should contain numbers from 1 to the largest number in the set. 
Their order or repetition are irrelevant.
