Definition of subsequence : subsequence is a term used to mean a sequence derived from a sequence S by discarding some of its terms.
-- from mathworld

So, in the above example 2 5 is a subsequence of the given sequence.

Very easy problem
As the numbers are all non-negative, when you are taking input just store the number in an array if the number is not equal to 0. And later just print the array(with no trailing spaces).
