Problem

Most programmers will tell you that one of the ways to improve your performance in competitive programming is to practice a lot of problems.

Our Chef took the above advice very seriously and decided to set a target for himself.

• Chef decides to solve at least $10$ problems every week for $4$ weeks.

Given the number of problems he actually solved in each week over $4$ weeks as $P_1, P_2, P_3,$ and $P_4$, output the number of weeks in which Chef met his target.

Input Format

There is a single line of input, with $4$ integers $P_1, P_2, P_3,$ and $P_4$. These are the number of problems solved by Chef in each of the $4$ weeks.

Output Format

Output a single integer in a single line - the number of weeks in which Chef solved at least $10$ problems.

Constraints

• $1 \leq P_1, P_2, P_3, P_4 \leq 100$

Sample 1:

Input

Output

12 15 8 10

3

Explanation:

Chef solved at least $10$ problems in the first, second and fourth weeks. He failed to solve at least $10$ problems in the third week. Hence, the number of weeks in which Chef met his target is $3$.

Sample 2:

Input

Output

2 3 1 10

1

Explanation:

Chef solved at least $10$ problems in the fourth week. He failed to solve at least $10$ problems in all the other three weeks. Hence, the number of weeks in which Chef met his target is $1$.

Sample 3:

Input

Output

12 100 99 11

4

Explanation:

Chef solved at least $10$ problems in all the four weeks. Hence, the number of weeks in which Chef met his target is $4$.

Sample 4:

Input

Output

1 1 1 1

0

Explanation:

Chef was not able to solve at least $10$ problems in any of the four weeks. Hence, the number of weeks in which Chef met his target is $0$.
