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
).
Input
The only line of the input contains four positive integers x1,x2,x3,x4
(2≤xi≤109) — numbers written on a board in random order. It is guaranteed that the answer exists for the given number x1,x2,x3,x4
.
Output
Print such positive integers a
, b and c that four numbers written on a board are values a+b, a+c, b+c and a+b+c written in some order. Print a, b and c
in any order. If there are several answers, you can print any. It is guaranteed that the answer exists.
