Polycarp has guessed three positive integers $a$, $b$ and $c$. He keeps these numbers in secret, but he writes down four numbers on a board in arbitrary order — their pairwise sums (three numbers) and sum of all three numbers (one number). So, there are four numbers on a board in random order: $a+b$, $a+c$, $b+c$ and $a+b+c$.

You have to guess three numbers $a$, $b$ and $c$ using given numbers. Print three guessed integers in any order.

Pay attention that some given numbers $a$, $b$ and $c$ can be equal (it is also possible that $a=b=c$).
