Consider the following method, which is intended to return the greatest absolute difference between any pair of corresponding elements in the int arrays pred and act.
/** Precondition: pred and act have the same non-zero length. */
public static int diff(int[] pred, int[] act)
{
int num = Integer.MIN_VALUE;
for (int i =0; i < pred.length; i++)
{
/* missing code */
}
return num;
}
Which of the following code segments can be used to replace /* missing code */ so that diff will work as intended?
Responses
if (pred[i]< act[i])
{
num = act[i]- pred[i];
}
if (pred[i]< act[i]){ num = act[i]- pred[i]; }
if (pred[i]> act[i])
{
num = pred[i]- act[i];
}
if (pred[i]> act[i]){ num = pred[i]- act[i]; }
if (pred[i]- act[i]> num)
{
num = pred[i]- act[i];
}
if (pred[i]- act[i]> num){ num = pred[i]- act[i]; }
if (Math.abs(pred[i]- act[i])< num)
{
num = Math.abs(pred[i]- act[i]);
}
if (Math.abs(pred[i]- act[i])< num){ num = Math.abs(pred[i]- act[i]); }
if (Math.abs(pred[i]- act[i])> num)
{
num = Math.abs(pred[i]- act[i]);
}
