Problem Statement

Is it possible to get a sum of $B$ when throwing a die with six faces $1,2,\ldots,6$ $A$ times?

Constraints

• $1 \leq A \leq 100$
• $1 \leq B \leq 1000$
• $A$ and $B$ are integers.

Input

Input is given from Standard Input in the following format:

$A$ $B$

Output

If it is possible to get a sum of $B$, print Yes; otherwise, print No.

Sample Input 1

2 11

Sample Output 1

Yes

There are two ways to get a sum of $11$ when throwing a $6$-faced die twice:

• getting $6$ in the first throw and $5$ in the second throw;
• getting $5$ in the first throw and $6$ in the second throw.

Sample Input 2

2 13

Sample Output 2

No

There is no way to get a sum of $13$ when throwing a $6$-faced die twice.

Sample Input 3

100 600
