Each of the squares has a $2$\\-character name determined as follows.\n\n*   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.\n*   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.\n\nFor instance, the bottom-left square is named `a1`, the bottom-right square is named `h1`, and the top-right square is named `h8`.\nYou are given $8$ strings $S_1,\\ldots,S_8$, each of length $8$, representing the state of the grid.  \nThe $j$\\-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.
