Problem Statement

In Japan, there are four major categories of ice cream type products:

  • an ice cream type product with at least $15$ percent milk solids and at least $8$ percent milk fat is called an ice cream;
  • an ice cream type product with at least $10$ percent milk solids and at least $3$ percent milk fat that is not an ice cream is called an ice milk;
  • an ice cream type product with at least $3$ percent milk solids that is not an ice cream or an ice milk is called a lacto ice;
  • an ice cream type product that is not an ice cream, an ice milk, or a lacto ice is called a flavored ice.

Here, milk solids consist of milk fat and milk solids-not-fat.
AtCoder's famous product Snuke Ice contains $A$ percent milk solids-not-fat and $B$ percent milk fat.
Which of the categories above does Snuke Ice fall into?
Print your answer as an integer according to the Output section.

Constraints

  • $0 \le A \le 100$
  • $0 \le B \le 100$
  • $A + B \le 100$
  • $A$ and $B$ are integers.

Input

Input is given from Standard Input in the following format:

$A$ $B$

Output

Print an integer as follows:

  • if Snuke Ice is an ice cream, print $1$;
  • if Snuke Ice is an ice milk, print $2$;
  • if Snuke Ice is a lacto ice, print $3$;
  • if Snuke Ice is a flavored ice, print $4$.

Sample Input 1

10 8

Sample Output 1

1

This product contains $10$ percent milk solids-not-fat and $8$ percent milk fat, for a total of $18$ percent milk solids.
Since it contains not less than $15$ percent milk solids and not less than $8$ percent milk fat, it is an ice cream; the correct output is $1$.


Sample Input 2

1 2

Sample Output 2

3

Since it contains exactly $3$ percent milk solids, it is not an ice cream or an ice milk but is a lacto ice; the correct output is $3$.


Sample Input 3

0 0

Sample Output 3

4

It is a flavored ice.

Input
