Write an iterative method to compute the power of x n for non-negative n.

What will be an ideal response?

```
public static int iterativePower(int x, int n)
{
int result = 1;
if(n < 0)
{
System.out.println("Illegal argument to power");
System.exit(0);
}
for(int i = 1; i <= n; ++i)
result = result * x;
return result;
}

```
