Do You Know Your ABCs?

문제

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

Elsie has three positive integers $AA$, $BB$, and $CC$ ($A\le B\le CA\backslash le\; B\backslash le\; C$). These integers are supposed to be secret, so she will not directly reveal them to her sister Bessie. Instead, she gives Bessie seven (not necessarily distinct) integers in the range $1\dots {10}^{9}1\; \backslash ldots\; 10^9$, claiming that they are $AA$, $BB$, $CC$, $A+BA+B$, $B+CB+C$, $C+AC+A$, and $A+B+CA+B+C$ in some order.

Given a list of these seven numbers, please help Bessie determine $AA$, $BB$, and $CC$. It can be shown that the answer is unique.

입력

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

출력

Print $AA$, $BB$, and $CC$ separated by spaces.
