B'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 ). The only line of the input contains four positive integers x_1, x_2, x_3, x_4 ( 2 <= x_i <= 10^9 ) -- numbers written on a board in random order. It is guaranteed that the answer exists for the given number x_1, x_2, x_3, x_4 . 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. '...
