Computer Science for IGCSE & O level - Algorithm Design And Problem Solving (Section 5 - No. 29)

What is the goal of using "normal data" in testing an algorithm?

To check if the algorithm works correctly with values at the boundaries.

To test the algorithm with valid and expected inputs.

To assess the algorithm's response to invalid inputs.

To expose unexpected behavior in the algorithm.

Normal data is used to confirm that the algorithm produces the expected output for typical input values.
