    Question

    Given the following code snippet, what will be the output when the function findMax is called with the array arr = [1, 5, 3, 9, 2]? 

    def findMax(arr):

        max_val = arr[0]

        for num in arr:

            if num > max_val:

                max_val = num

        return max_val

    result = findMax([1, 5, 3, 9, 2])

    print(result)

    A 1 Correct Answer Incorrect Answer
    B 5 Correct Answer Incorrect Answer
    C 9 Correct Answer Incorrect Answer
    D 3 Correct Answer Incorrect Answer
    E 2 Correct Answer Incorrect Answer

    Solution

    In the provided code snippet, the findMax function is designed to find the maximum value in an array. It initializes max_val with the first element of the array and iterates through each element. If it finds an element greater than max_val, it updates max_val. For the input [1, 5, 3, 9, 2], the function correctly identifies 9 as the maximum value, which is returned and printed. Why Other Options Are Wrong: A) 1: This option is incorrect because 1 is the initial value of max_val, but it is not the maximum value in the array. B) 5: This option suggests that 5 is the maximum, which is incorrect as the loop finds 9 to be greater than 5. D) 3: This option is incorrect because 3 is neither the maximum value nor is it greater than any of the subsequent numbers in the array. E) 2: This option is incorrect as 2 is the smallest number among the last two elements in the array and does not represent the maximum.
