arrayMystery

Language/Type: Java arrays array mystery
Author: Marty Stepp

Consider the following method:

public static void arrayMystery(int[] a) {
     for (int i = a.length - 2; i > 0; i--) {
          if (a[i - 1] < a[i + 1]) {
                a[i] += a[i - 1];
          } else {
                a[i] += a[i + 1];
          }
     }
}

Indicate in the right-hand column what values would be stored in the array after the method arrayMystery executes if each integer array below is passed as a parameter to it.

int[] a1 = {1, 2, 3}; arrayMystery(a1);
int[] a2 = {8, 2, 3, 1, 6}; arrayMystery(a2);
int[] a3 = {1, 1, 1, 1, 1, 1}; arrayMystery(a3);
int[] a4 = {40, 10, 25, 5, 10, 30}; arrayMystery(a4);
int[] a5 = {15, 6, -1, 4, 8, -2, 7, 4}; arrayMystery(a5);
