Write a method which eliminates pair numbers from continuous stream of numbers read one at a time until no more numbers are returned. Numbers are not read in order and there can be duplicates. For example : {3,7,9,41,21, 56, 8, 2} should become {9,41,21,56}, so pairs like 2,3 and 7,8 needs to be eliminated. out of 10

There is no upper limit how many incoming numbers there may be. For testing purposes I have used max 1000. At some point this may cause exception if input numbers max is very high.
