a$)$ Draw the corresponding Control Flow Graph. just draw it$.$

b$)$ Draw the prime decomposition tree. $[4$ points$]$

c$)$ How many test cases are needed $($at a minimum$)$ to achieve the following coverage critera? Please list the identified test cases $[4$ points$]$

Simple path coverage

Basis path coverage

d$)$ Provide provide all $($partial$)$ paths to achieve all DL$-$path coverage with respect to variable $\text{'}$a$\text{'}.$ All paths should be defined in terms of nodes traversed in the CFG$.[4$ points$)$
