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. *
