Exercise $1\mathrm{.}4(10$ points$)$

Exploit the results stemmed from analyzing the respresentation of the text string MSG considered in Exercise $1\mathrm{.}3$ to address the following questionnaire:

$($a$)$ What is the integer value that represents the blank space $(\text{'}\text{'})$ as a character?

$($b$)$ The text string MSG may be parsed into three parts: s$\_1=$ 'EEL$3002$L$\text{'},$ s$\_2=\text{'}$is$\text{'},$ and s$\_3=$ 'usefull'. Construct a numeric matrix S$\_$MSG of integer values consisting of three rows that represent the text strings s$\_1,$ s$\_2$ and s$\_3,$ respectively. $($Caution: The rows must have the same length.$)$

$($c$)$ Use the commands disp combined with char to reveal the text strings stored in S$\_$MSG$.$
