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.
