Question

What element values are stored in the following array?

int[] a = {1, 7, 5, 6, 4, 14, 11};
for (int i = 0; i < a.length - 1; i++) {
if (a[i] > a[i + 1]) {
a[i + 1] = a[i + 1] * 2;
}
}

Answer 1

The array 'int[] a = {1, 7, 5, 6, 4, 14, 11}' will be modified by a loop that doubles the next element if the current one is greater. The final array after the loop will be {1, 7, 10, 12, 8, 14, 11}.

Step-by-step explanation:

The question involves understanding the operation performed by the given code snippet on the array. After executing the code, the elements stored in the array will be changed based on the conditional statement within the for loop that compares each element with the one that follows it. If the current element is greater than the next element, the next element will be doubled. Here is how the array will change after the loop executes:

• After comparing the first element (1) with the second (7), no change occurs because 1 is not greater than 7.
• Comparing 7 with 5, since 7 is greater, we double the 5 to get 10. The array is now {1, 7, 10, 6, 4, 14, 11}.
• The next comparison, between 10 and 6, triggers the condition; 6 gets doubled to 12. The array is now {1, 7, 10, 12, 4, 14, 11}.
• Since 12 is greater than 4, the fourth comparison doubles 4 to 8. The array is now {1, 7, 10, 12, 8, 14, 11}.
• The condition does not trigger for 12 and 14, nor for 14 and 11, so the remaining elements stay unchanged.

Therefore, the final values stored in the array will be {1, 7, 10, 12, 8, 14, 11}.
