Question

Which of the following is a suitable lookup table that can be used in the uniform binary search?(N is the number of elements in the array and the delta array is global)
a)

public static void make_delta(int N) 
{
       int power = 1;
       int i = 0;
       do 
       {
            int half = power;
            power <<= 1;
            delta[i] = (N + half) / power;
       } 
       while (delta[i++] != 0);
}

b)

public static void make_delta(int N) 
{
       int power = 0;
       int i = 0;
       do 
       {
            int half = power;
            power <<= 1;
            delta[i] = (N + half) / power;
       } 
       while (delta[i++] != 0);
}

c)

public static void make_delta(int N) 
{
       int power = 1;
       int i = 0;
       do 
       {
            int half = power;
            power >>= 1;
            delta[i] = (N + half) / power;
       }
       while (delta[i++] != 0);
}

d)

public static void make_delta(int N) 
{
       int power = 1;
       int i = 0;
       do 
       {
            int half = power;
            power <<= 1;
            delta[i] = (N - half) / power;
       } 
       while (delta[i++] != 0);
