Samples

Input #1

2 5 2

Output #1

5

The first and third dice both showed $2$, so we should print the number on the remaining dice, which is $5$.

Input #2

4 5 6

Output #2

0

Any two numbers are different, so we should print $0$.

Input #3

1 1 1

Output #3

1

Any two numbers are the same. Whichever two dice we choose, the number on the remaining dice will be $1$.
