$9\mathrm{.}3$ A program computes the row sums

$C_i={\displaystyle \underset{j=1}{\overset{n}{}}}{a}_{ij}$

of an array A that is $100$ by $100.$ Assume that the computer uses demand paging with a page size of $1000$ words, and that the

amount of main memory allotted for data is five page frames. Is there any difference in the page fault rate if A were stored in virtual

memory by rows or columns? Explain.
