### Prompt

Construct a cpp code solution to the problem outlined:

Blackjack is a type of card game played in casinos, where the game is played using cards with numbers from 1 to 13. The score of each card is decided as follows.

* 1 is 1 point or 11 points
* From 2 to 9, the score is as written.
* 10 points from 10 to 13



There are several participants in this game, including parents, each with several sets of cards. This set of cards is called a hand. The hand score is the total of the card scores. The calculation shall be performed as follows.

* If the total score of the cards is greater than 21, the score of the hand is set to 0.
* As the score of the card, 1 may be calculated as 1 point or 11 points, but the one with the maximum hand score shall be selected.



Create a program that uses the information of the cards dealt as input and outputs the score of the hand.



Input

A sequence of multiple datasets is given as input. The end of the input is indicated by a single line of zeros. Each dataset is given in the following format:


c1 c2 ... cn


The integer ci (1 ≤ ci ≤ 13) written on the i-th card is given to each line, separated by blanks. The number of cards n does not exceed 100.

The number of datasets does not exceed 200.

Output

The score of the hand is output to one line for each data set.

Example

Input

1
7 7 7
7 7 8
12 1
10 1 1
0


Output

11
21
0
21
12
