I have an array of numbers should return true if 2 adjacent numbers divide by 10.

For now, my code return always `false`.

*My attempt:*

```
public static boolean divideByTen(int arr[], int num) {
    int i = num - 1;

    if (i > 0) {
        divideByTen(arr, num - 1);

        if (arr[i] + arr[i - 1] % 10 == 0)
            return true;
    }
    return false;
}

```
