Suppose you choose 14 of the integers from 1 to 1111, inclusive.
Show that in any such set there are two subsets having the same sum for their elements.
It is not necessarily true that the union of the two subsets is the full 14 element set.

Despite repeated reminders you are still indulging in extreme indecency by posting such irrelevant and idiotic comments.
I would strongly urge you from desisting in doing so.
