### Statement

Artem made up three integers and told Eugene the average value of every pair of them. Eugene easily restored original integers. Now you try to do the same!

### Input format

Input contains three numbers: x, y and z. Numbers are either integers or have fractional part of exactly 0.5. At least one number is not zero.

### Output format

Output original integers in non-descending order (input data are such that the original numbers will turn out to be integer).

### Constraints

− 108 ≤ x, y, z ≤ 108

### Notes on sample

In the sample x = 1.5, y = 2 and z = 3.5. These are pairwise averages for a = 0, b = 3 and c = 4. Indeed:

a + b2 = 0 + 32 = 1.5 = x;

a + c2 = 0 + 42 = 2 = y;

b + c2 = 3 + 42 = 3.5 = z.
