Consider the code segment below, where arr is a one-dimensional array of integers.
int sum = 0;
for (int n : arr)
{
sum = sum + 2 * n;
}
System.out.print(sum);
Which of the following code segments will produce the same output as the code segment above?
int sum = 0;
for (int k = 0; k < arr.length; k++)
{
sum = sum + 2 * k;
}
System.out.print(sum);
int sum = 0;
for (int k = 0; k <= arr.length; k++)
{
sum = sum + 2 * k;
}
System.out.print(sum);
int sum = 0;
1; k <= arr.length; k++)
for (int k
{
sum = sum + 2 * k;
}
System.out.print(sum);
int sum = 0;
for (int k = 0; k < arr.length; k++)
{
sum = sum + 2 * arr[k];
D
}
System.out.print(sum);
int sum = arr[0];
for (int k = 1; k <= arr.length; k++)
{
sum = sum + 2 * arr[k];
}
System.out.print(sum);
