write another class method called shrink similar to exand but where the new size of the table is actually smaller than the old one. It should have the same parameters as the functions expand, but the for loop should be bases on the new number of rows, and the nubmer of elements to be copied in the call to arrayCopy should be equal to the new number of columns.
