question

A programmer wrote the program below. The program uses a list of numbers called numList. The program is intended to display the sum of the numbers in the list.
 sum ← numList [1]
 FOR EACH value IN numList
 sum ← sum + value
 DISPLAY sum
 In order to test the program, the programmer initializes numList to [0 , 1 , 4 , 5]. The program displays 10, and the programmer concludes that the program works as intended. Which of the following is true?

choices

  1. The conclusion is correct; the program works as intended.
  2. The conclusion is incorrect; the program does not display the correct value for the test case [0, 1, 4, 5].
  3. The conclusion is incorrect; using the test case [0, 1, 4, 5] is not sufficient to conclude the program is correct.
  4. The conclusion is incorrect; using the test case [0, 1, 4, 5] only confirms that the program works for lists in increasing order.
