Answer 1

To print a 1 dimension array (In computing it is an Array. In mathematics it is a Matrix) you require a loop.

for (i=0; i print arrayData[i]
}

Now for a 2 dimension array you require 2 loops

for (i=0; i for (j=0; j print arrayData[i][j]
}
print newLine
}

Now you can do the rest. Have I got the programming language wrong? Well what hint did you give me!
