Question

What is the return value of the function call BS(array, 0, 9, 45), where array is an array declared as

int array[]={3, 10, 13, 20, 35, 45, 67, 77, 82, 90};

The recursive function BS is defined as:

int BS(int array[], int first, int last, int value)

{
    int mid;
      
    if (first > last)
        return -1;
    else {
            mid = (first + last) / 2;

            if (value == array[mid])
                return mid;
            else if (value < array[mid])
                return BS(array, first, mid - 1, value);
            else if (value > array[mid])
                return BS(array, mid + 1, last, value);
        }
}
