1 3 5

Sample Output

Explanation
There are 10 stones on mars i.e. 1, 2, …., 10 which weigh 1, 2, ….., 10 respectively.
Of which 3 Stones (1, 3 and 5) are available on Earth.
So the maximum unique stones Rob can bring from Mars is 2, such that the Maximum Size of Bag doesn’t exceed.
(2, 4) (2, 6) (2, 7) (2, 8) (4, 6) and so max. 2
