Problem Statement

There is a grid with $2$ rows and $2$ columns.

Each cell of the grid contains exactly one of A, B, C, and D, and the characters written in the $4$ cells are distinct. The cell at the $i$-th row from the top and the $j$-th column from the left contains $S_{i,j}$.

If the cell containing A and the cell containing D are adjacent, that is, they share an edge, print Yes; otherwise, print No.

Constraints

• $S_{i,j}$ is one of A, B, C, and D.
• If $(i_1,j_1)\neq (i_2,j_2)$, then $S_{i_1,j_1}$ and $S_{i_2,j_2}$ are distinct.

Input

The input is given from Standard Input in the following format:

S_{1,1}S_{1,2}
S_{2,1}S_{2,2}

Output

Print the answer in a single line.
