Description
Score : $200$ points
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 isb,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 is2,3,4,5,6,7,8, 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.
Constraints
- $S_i$ is a string of length $8$ consisting of
.and*. - The character
*occurs exactly once among $S_1,\ldots,S_8$.

令 $c_i$ 表示小写字母表中的第 $i$ 个字母。 有一个 $8\times 8$ 大小的棋盘，其中从下至上第 $i$ 行，从左至右第 $j$ 列被表示为 $(c_j,i)$。 现在棋盘上有一个用 `*` 表示的棋子，剩下的都是 `.`，输出棋子的坐标。 Translated by @[Zealous_YH](https://www.luogu.com.cn/user/399150)Output
问题描述
在国际象棋棋盘上找到一个棋子。
我们有一个由8行和8列正方形组成的网格。每个正方形都有一个由以下方法确定的2个字符的名称。
- 从左数第1列的正方形名称的第一个字符是
a。类似地，从左数第2、3、…、8列的正方形名称的第一个字符分别是b、c、d、e、f、g和h。 - 从下数第1行的正方形名称的第二个字符是
1。类似地，从下数第2、3、…、8行的正方形名称的第二个字符分别是2、3、4、5、6、7和8。
例如，左下角的正方形名称是a1，右下角的正方形名称是h1，右上角的正方形名称是h8。
给你8个字符串$S_1,\ldots,S_8$，每个长度为8，表示网格的状态。
如果从上数第$i$行和从左数第$j$列的正方形上有一个棋子，则$S_i$的第$j$个字符是*，否则是.。
在$S_1,\ldots,S_8$中，字符*出现且仅出现一次。
找出有棋子的正方形的名称。
约束条件
- $S_i$是一个由
.和*组成的长度为8的字符串。 - 在$S_1,\ldots,S_8$中，字符
*出现且仅出现一次。
