Hi coders...M stuck here.. I want this code to return 1 if an element in the array has exactly one non zero neighbor. Like arr1

Question

public class Program
{
public static int erachek(int [] arr) {

for(int i=0;i<arr.length;i++){
if (arr[i]>0){
return 1;
}

}
return 0;
}

public static void main(String [] args){

int [] arr1={0,3,2};
int [] arr2={7,6,9};

System.out.println (erachek (arr1));
System.out.println (erachek (arr2));
}
}

Answer 1

But condition is true for arr2 too as the first and the last elements for example have exactly 1 non zero neighbor.

Answer 2

Then your question is wrong. It should be: the method returns 1 if there is no element in the array with two nonzero neighbors. Otherwise 0.

And what should it return if both neighbors are zeros.

Answer 3

in arr2 (6)has more than one non zero neighbor

Answer 4

therefore it shud return 0
