Question

Consider the following method.

public void mystery(int[] data)
{
for (int k = 0; k < - 1; k++)
data[k + 1] = data[k] + data[k + 1];
}

The following code segment appears in another method in the same class.

int[] values = {5, 2, 1, 3, 8};
mystery(values);
for (int v : values)
System (v + " ");
System.out.println();

What is printed as a result of executing the code segment?

Answer 1

The code will output the values 5 7 8 11 19.

Step-by-step explanation:

The given code snippet defines a method called mystery that takes an array of integers as input. Inside the method, a for loop is used to iterate over the elements of the array, starting from index 0 and going up to one less than the length of the array. In each iteration, the value at the next index is updated by adding the current value and the next value together.

In the code segment that follows, an array named values is created and initialized with the values {5, 2, 1, 3, 8}. The mystery method is then called with the values array as the argument. After that, a for each loop is used to print each element of the values array, separated by a space. The output of this code segment would be: 5 7 8 11 19.
