A two-dimensional array myArray is to be created with the following contents. {{0, 0, 3},

{0, 0, 0},

{7, 0, 0}}

Which of the following code segments can be used to correctly create and initialize myArray ?

I. int myArray[][] = new int[3][3];
myArray[0][2] = 3;
myArray[2][0] = 7;

II: int myArray[][] = new int[3][3];
myArray[0][2] = 7;
myArray[2][0] = 3;

III: int myArray[][] = {{0, 0, 3}, {0, 0, 0}, {7, 0, 0}};

A) I only.

B) II only.

C) III only.

D) I and III.

E) II and III.

Suppose there is a relation r(a, b, c) with a b+-tree index with search keys (a, b).1. what is the worst-case cost of finding records satisfying 10 < a < 50 using this index, in terms of the number of records n1, retrieved and the height h of the tree? 2. what is the worst-case cost of finding records satisfying 10 < a < 50 and 5 < b < 10 using this index, in terms of the number of records n2 that satisfy this selection, as well as n1 and h defined above? 3. under what conditions on n1 and n2, would the index be an efficient way of finding records satisfying the condition from part (2)?
