how to count contiguous and common zeros in various arrays

[Shel22]

Hi Friends!

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

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}

...........

How can I count the common zero sequences and there indexes for all arrays?

sample output for the above arrays:

Index Nim_of_zeros

3 1

7 2

12 2

Could you anyone help me?

I find that the concept of a state machine can be very helpful in programming. You could solve your program with a state machine that has two states: common zero (CZ) and not common zero (NCZ). Set the initial conditions and step through the array elements, using logic based on the current state and what is in the next element of the arrays.
