Nezavi [6.7K]

Answer:

The conclusion is incorrect; using the test case [0, 1, 4, 5] is not sufficient to conclude the program is correct.

Explanation:

From the code snippet given, we cannot conclude that the test case is sufficient.

One of the reasons is because the test case contains only integer variables.

Tests need to be carried out for other large and floating points numerical data types such as decimal, double, float, etc. except that when it's known that the inputs will be of type integer only else, we can't rush into any conclusion about the code snippet

Another reason is that input are not gotten at runtime. Input gotten from runtime environment makes the program flexible enough.

Lastly, the array length of the array in the code segment is limited to 4. Flexible length needs to be tested before we can arrive at a reasonable conclusion.
