problem_description: Statement
  
  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.
