each case? (c) Are the combinations generated in (b) unique in the
sense that another set of combinations would also be satisfactory
and as small in number?
2.23Construct a sample implementation
Ito show that the
application of heuristic H
2
from Table 2.4 will leave out at least
one test that would have detected the error in
I.
2.24Consider the following modified versions of heuristics H
1
and H
4
given in Table 2.4.
H
1
:Enumerate any one combination of inputs to n
1
and n
2
such
that n
1
=n
2
=0.
H
4
:Enumerate all combinations of inputs to n
1
and n
2
such that
n
1
=n
2
=1.
Discuss why the above modifications are undesirable (or
desirable).
