C++ Code, Function below is not a member function of Sequence class:

void
subtractX(Sequenceint>& s,
int& x) //! updates s //! clears x //! ensures: s = #s with all corresponding values of s reduced by value in #x {
for
(int
k = 0, z = s.length(); k < z;="" k++)="" {="" s1.1,="" s1.2,="" s1.3,="">
int
y; s.remove(k, y); // s2 y -= x; // s3 s.add(k, y); // s4 } // end for x.clear(); // s5 } // END subtractX

For the function above,

a. Draw the code diagrams with labels for statements and branches.

b. Provide test cases for statement, branch, and path coverages (properly identifying all the test cases with correct labels and the respective function).
