9. Consider the following function: int rec(int array[], int n) { int p; if (n < 0) if (array[n] < return 0; 0) return 10; else { System.out.println(array[n]); array[n] + rec (array,n-2); System.out.println(p); p = return p; } } A. What is printed? Show your box trace. int[] arx {60, 40, 20, 50, 90, 80, 30, 10}; System.outprintln(rec (arr,7)); B. What is printed? Show your box trace. { 60, 40, -20, 50, 90, 80, 30, 10, 70}; int[] arr = System.outprintln(rec(arr,8));

d) Prepare a brief report (250 words) comparing the two algorithms

What do parentheses do in mathematical equations?   a. Ensure addition functions are performed before subtraction functions   b. Ensure multiplication functions are performed before division functions   c. Ensure multiplication functions are performed before addition functions   d. Ensure that whatever operation is inside the parentheses is performed first
