Case study: Exam forms depends on course type values: "theoretical $"(T),$ "math" $(M)$ and "programming"$($P$),$ The following method returns what kind of exam to conduct. Apply ISP $($Input space partition$)$ method: a$)$ interface based approach, b$)$ functionality based approach. Coverage criteria is All Combinations. Show all valid and invalid combinations and their outputs.

String defineExam $($String coursetype, boolean lab$)($

return exam;

$\}$

exam variable values are: "multiple$-$choice"$($M$),$ "essay"$($E$)$ and "project"$($P$).$

Interface based table

$\backslash$table$[[$input$,$Blocks,$],[$coursetype$,,],[$lab$,,],[$Functionality based table,Blocks,$],[$output$,,],[$exam$,,]]$

Given class Course as follows: By using states variable values taken from question$1$ draw the annotated FSM diagram to describe states of class Course. States variable values should be taken from question$1.$ Find all Test Paths for Edge$-$Pair coverage of FSM$.$

class course f
