Computer Science for IGCSE & O level - Algorithm Design And Problem Solving (Section 13 - No. 32)
What is the primary goal of applying abnormal test data?
To determine if the data is of the correct type
To ensure that the algorithm works.
To determine if the algorithm responds correctly to invalid input.
To verify the presence of the data.
Explication
Abnormal/erroneous data is used to make sure the algorithm handles invalid input properly.
