> 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. ## Constraints * $S_i$ is a string of length $8$ consisting of `.` and`*`. * The character `*` occurs exactly once among $S_1,\ldots,S_8$. ## Input The input is given from Standard Input in the following format: $S_1$ $S_2$ $S_3$ $S_4$ $S_5$ $S_6$ $S_7$ $S_8$ [samples]
