Do You Know Your ABCs?

Farmer John's cows hold a daily online gathering on the "mooZ" video meeting platform. For fun, they have invented a simple number game to play during the meeting.

Elsie has three positive integers $A$, $B$, and $C$ ($A\le B\le C$). These integers are supposed to be secret, so she will not tell them directly to her sister Bessie. Instead, she gives Bessie seven integers in the range $1 \ldots 10^9$ (not necessarily distinct), claiming that they are $A$, $B$, $C$, $A+B$, $B+C$, $C+A$, and $A+B+C$ in some order.

Given these seven numbers, help Bessie determine $A$, $B$, and $C$. The answer is unique.

The only line of input contains seven space-separated integers.

Print $A$, $B$, and $C$, separated by spaces.
