15. The two-dimensional array MAT is used to store randomly generated integers in the range from 0 to 9. In the MAT array, some numbers can be repeated multiple times and other numbers may not appear at all (see Figure 1). Figure 1: Example data stored in the MAT array [0] [1] [2] [3] [4] [5] [6] [0] 0 2 5 9 3 6 1 [1] 0 2 9 0 7 0 0 [2] 4 2 7 9 5 7 1 [3] 7 2 3 1 5 4 0 [4] 3 6 3 9 9 6 0 [5] 7 4 3 1 7 9 3 [6] 3 9 6 4 2 2 4 (This question continues on the following page) (Question 15 continued) The one-dimensional COUNT array will show how many times each of the randomly generated numbers is found in the MAT array (see Figure 2). Figure 2: The content of the COUNT array [0] [1] [2] [3] [4] [5] [6] [7] [8] [9] 7 4 6 7 5 3 4 6 0 7 Figure 2 shows that number 4 occurs 5 times (COUNT[4]=5) in the MAT array.
