Score : $100$ points
Problem Statement
You are given three integers, $A$, $B$ and $C$.
Among them, two are the same, but the remaining one is different from the rest.
For example, when $A=5,B=7,C=5$, $A$ and $C$ are the same, but $B$ is different.
Find the one that is different from the rest among the given three integers.
Constraints
- $-100 \leq A,B,C \leq 100$
- $A$, $B$ and $C$ are integers.
- The input satisfies the condition in the statement.
Input
Input is given from Standard Input in the following format:
Output
Among $A$, $B$ and $C$, print the integer that is different from the rest.
5 7 5
7
This is the same case as the one in the statement.
1 1 7
7
In this case, $C$ is the one we seek.
