You have decided to give an allowance to your child depending on the outcome of the game that he will play now. The game is played as follows: * There are three "integer panels", each with a digit between $1$ and $9$ (inclusive) printed on it, and one "operator panel" with a `+` printed on it. * The player should construct a formula of the form $X + Y$, by arranging the four panels from left to right. (The operator panel should not be placed at either end of the formula.) * Then, the amount of the allowance will be equal to the resulting value of the formula. Given the values $A, B$ and $C$ printed on the integer panels used in the game, find the maximum possible amount of the allowance. ## Constraints * All values in input are integers. * $1 \leq A, B, C \leq 9$ ## Input Input is given from Standard Input in the following format: $A$ $B$ $C$ [samples]

Samples

Input #1

1 5 2

Output #1

53

The amount of the allowance will be $53$ when the panels are arranged as `52+1`, and this is the maximum possible amount.

Input #2

9 9 9

Output #2

Input #3

6 6 7

Output #3
