Where's Snuke?

There is a grid with $H$ rows and $W$ columns. The square at the $i$\-th row and $j$\-th column contains a string $S_{i,j}$ of length $5$. The rows are labeled with the numbers from $1$ through $H$, and the columns are labeled with the uppercase English letters from `A` through the $W$\-th letter of the alphabet.  Exactly one of the squares in the grid contains the string `snuke`. Find this square and report its location. For example, the square at the $6$\-th row and $8$\-th column should be reported as `H6`. ## Constraints * $1≦H, W≦26$ * The length of $S_{i,j}$ is $5$. * $S_{i,j}$ consists of lowercase English letters (`a`\-`z`). * Exactly one of the given strings is equal to `snuke`. ## Input The input is given from Standard Input in the following format: $H$ $W$ $S_{1,1}$ $S_{1,2}$ $...$ $S_{1,W}$ $S_{2,1}$ $S_{2,2}$ $...$ $S_{2,W}$ $:$ $S_{H,1}$ $S_{H,2}$ $...$ $S_{H,W}$ [samples]
