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`.
h,w=map(int,input().split())
a=[input().split() for _ in range(h)]

    if(a[i][j]=="sunuke"):
      print(chr(65+j)+str(i+1))
