Problem Statement

In a certain region, Koda City in Yuki Prefecture, a city council election is being held.

To run in a city council election, something called an election deposit is required. (Election deposit: Wikipedia)
To stand as a candidate, one must deposit $30$ man-yen (1 man-yen = 10,000 yen) at the deposit office.
If the candidate's vote count exceeds $1$ over $10$ of the total number of valid votes, the deposit is returned in full;
if it is $1$ over $10$ or less, the deposit is forfeited in full and paid to the city.
Normally a procedure is required for the return, but here it is assumed to be returned automatically.

In Koda City, Yuki Prefecture, $N$ people ran, and each candidate received $C_i$ ($1 \le i \le N$) votes.
Find the total amount of deposits paid to Koda City, Yuki Prefecture after the election ends.

(Unrelated to the problem: the deposit amount and the forfeiture criteria differ depending on the type of election.)

Input

$N$
$C_1\ C_2\ \dots\ C_N$

All inputs are given as integers.
$1 \le N \le 100=10^2$
$0 \le C_i \le 1000000=10^6$

Output

Output the total amount paid to the city (in units of man-yen).
Print a newline at the end.
