Problem Statement

Locate a piece on a chessboard.

We have a grid with 8 rows and 8 columns of squares. Each of the squares has a 2-character name determined as follows.

• The first character of the name of a square in the 1-st column from the left is a. Similarly, the first character of the name of a square in the $2-nd, 3-rd, \ldots, 8-th$ column from the left is b, c, d, e, f, g, h, respectively.
• The second character of the name of a square in the 1-st row from the bottom is 1. Similarly, the second character of the name of a square in the $2-nd, 3-rd, \ldots, 8-th$ row from the bottom is 2, 3, 4, 5, 6, 7, 8, respectively.

For instance, the bottom-left square is named a1, the bottom-right square is named h1, and the top-right square is named h8.
You are given $8 strings S_1,\ldots,S_8$, each of length 8, representing the state of the grid.
The j-th character of S_i is * if the square at the i-th row from the top and j-th column from the left has a piece on it, and . otherwise.
The character $* occurs exactly once among S_1,\ldots,S_8$.
Find the name of the square that has a piece on it.
