Problem Statement

There are three cards on the desk, each with a positive integer written on it. The integers on the cards are $A$, $B$, and $C$.

You have chosen two cards and picked them up.

Find the maximum possible sum of the integers written on the picked cards.

Constraints

• $1 \\leq A,B,C \\leq 100$
• All values in input are integers.

Input

Input is given from Standard Input in the following format:

$A$ $B$ $C$

Output

Print the answer as an integer.

Sample Input 1

3 4 5

Sample Output 1

9

If you pick up two cards with $4$ and $5$, the sum of the integers will be $4+5=9$.

There is no way to pick up cards with a greater sum, so we should print $9$.

Sample Input 2

6 6 6

Sample Output 2

12

Whichever two cards you choose, the sum of the integers will be $12$.

Sample Input 3

99 99 98

Sample Output 3

198
