suppose you have a two$-$dimensional character array $x$ with $10$ rows and $31$ columns. for example, if the input is:

student@najah.edu

ahmad

muhannad

Inajah$1$

$2$najah$2$

$3$ najah$3$

$4$ najah$4$

$5$najah$5$

$6$ najah$6$

$7$ najan$7$

$8$ najah$8$

$9$najah$9$

the output is:

$9$najah$9$

$8$najahs

$7$najah$7$

$6$ najah$6$

$5$najah$5$

$4$ najah $4$

$3$najah$3$

$2$najah$2$

$1$najah$1$

student@najah.edu
