Counting Stars

People generally don’t care to give attention to stars in a moonlit night. In most cases the attention goes towards the moon. Sadly, you have to write a program now that can count the stars in the sky. For this problem a sky is a two dimensional grid. Empty pixel is denoted by a ‘.’ (ASCII value 46) and a non-empty pixel is denoted by a ‘’ (ASCII value 42). As a star is a very small object so it cannot occupy more than one pixel and in our sky two stars are never adjacent. So two or more adjacent non- empty pixels can denote some larger objects like moon, comet, sun or UFOs but they never represent a star. All the eight possible pixels around a pixel are adjacent to it. In the figure below the black pixel at the center have eight adjacent pixels. Of them three pixels are non-empty. .. . ..* Input The input file contains at most 1000 sets of inputs. The description of each set is given below: Each set starts with two integer number r and c (0 < r,c < 101), which indicates the row and column number of the image to follow. Next r rows describe the sky as mentioned in the problem statement. Input is terminated by a line containing two zeroes. Output For each set of input produce one line of output. This line contains a decimal integer which denotes the number of stars in the given sky. Sample Input 55 ..... ....* ....* ...*. .... 43 ... .. ... . 00 Sample Output 1 3
