In Nine Men's Morris game, the players try to place their pieces on adjacent points so that they can remove one of the opponent pieces. For example the pieces on b2, d2 and f2 are adjacent on a line. Similarly, the pieces on d7, d5 and d6 are also adjacent on a line. But the pieces on b4, c4 and e4 are not adjacent on a line.

Question: Write a program that reads the positions of 4 pieces and decides if any three are adjacent on a line.

Input specification: You will be given the coordinates of 4 pieces, a letter and an integer separated by a space.

Output specification: Show "Yes" if any three are adjacent on a line, or "No" otherwise.

Explanation: In the first sample, the pieces a7, d7, and g7 are aligned on a line.
In sample 2, no three pieces are aligned on a line.
