Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

Given
int[][] a = {1}, {2, 3), (4, 5, 6}, {7, 8, 9, 10);

System.out.println(a[0].length);
System.out.println(a[1][2] + a[3][3]);
int[][] m = a;
int c = a[2];

Consider the following code segment that includes a method called multiply. The multiply method is a sample method for the multiplication of an n by m array and an m by p array. Suppose the multiply method is invoked as shown after replacing the element indicated as x by a number. What number should replace x so that the b3[0][0] = 9 after the execution of b3 = multiply(b1,b2)? Note that the initializeArray method puts a O to every cell of the array passed to initializeArray. *
