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, what will be the value of the expression
a6[0][0]?
Note that the initializeArray method puts a 0 to every cell of the array
passed to initializeArray. *
