Answer
Exam answer
Index of the maximum element (19) : X[2][0] Index of the minimum element (2) : X[1][1]
Explanation
Lay the array out with its indices before reading off the answer: row 0 : X[0][0] = 4 X[0][1] = 5 row 1 : X[1][0] = 7 X[1][1] = 2 row 2 : X[2][0] = 19 X[2][1] = 4 row 3 : X[3][0] = 7 X[3][1] = 4 The largest value is 19, sitting in row 2, column 0. The smallest is 2, in row 1, column 1. The question asks for the INDEX, not the value — write it in the form X[row][column]. Answering "19 and 2" earns nothing.
