Description

Customer support department in an "Incomprehension Amateurs, Ltd" software company has call center for answering users' questions. Support prices are as follows:

So, for example, if user asks the same question three times, first receives incorrect answer, then correct one, and the third time correct answer with explanation, it will cost him 10 + 20 + (40 + 1 * 10) = 80 USD.

Customers are billed monthly according to call log. Company engineers review the log and for each question determine:

1. unique number, so the equivalent questions have same numbers,
2. whether the answer was correct,
3. whether the answer was short or included detailed enough explanation.

Given that data, your program must calculate the payment amount.

Input

Input file contains number of calls N followed by N triples q_i a_i x_i, where q_i is integer question number, a_i = 1 if the answer was correct, 0 otherwise, x_i = 1 if explanation was given, 0 otherwise.

Constraints

1 ≤ N ≤ 10000, 1 ≤ q_i ≤ 10⁶.

Output

Output file must contain a single number — payment amount.
