Integrate the algorithm outlined in Figure into a complete, user-friendly bisection subprogram. Among other things:

(a) Place documentation statements throughout the subprogram to identify what each section is intended accomplish.

(b) Label the input and output.

(c) Add an answer check that substitutes the root estimate into the original function to verify whether the final result is close to zero.

(d) Test the subprogram by duplicating the computation from Example 5.3 and 5.4.
