Problem Statement

You are given four strings $S_1$, $S_2$, $S_3$, and $S_4$.
Determine whether this sequence of strings has one of each of the following: H, 2B, 3B, and HR.
Here, it is guaranteed that every $S_i$ is H, 2B, 3B, or HR.

Constraints

• Each $S_i$ is H, 2B, 3B, or HR.

Input

Input is given from Standard Input in the following format:

$S_1$
$S_2$
$S_3$
$S_4$

Output

If the given sequence of strings has one of each of H, 2B, 3B, and HR, print Yes.
Otherwise, print No.
