Consider Program P9.7 in Figure 9.13. Suppose the following function trace trace(t) is obtained by executing the program against test t: main, f1, f2, main. (a) Draw the dynamic dependence graph from trace(t). (b) Now suppose a change is made in function f3. Will t be included in the regression test? (c) Will t be included in the regression test if a change is made to f1?
