how to count contiguous and common zeros in various arrays

Hi Friends!

If I have number of arrays(its 3 for instance and may vary) with fixed size (15), it consist of zeros and non-zeros

How to write a program to count the common zero sequences and there indexes of arrays?

eg:array1[15]={5,5,0,0,4,4,4,0,0,0,1,0,0,0,3}

array2[15]={1,0,0,0,0,7,7,0,0,3,0,0,0,0,2}

array3[15]={6,6,6,0,8,8,8,0,0,0,3,3,0,0,4}

...........


sample output for the above arrays:

Index==> Nim_of_zeros

3==> 1

7==> 2

12==> 2
