private static void constrain(int[] arr, int min, int max, int index)
{
if(index >= arr.length)
return;
if(arr[index] < min)
arr[index] = min;
if(arr[index] > max)

constrain(arr, min, max, index + 1);
}
The methods constrain each value in arr to be between min and max, inclusive.
This method should have a precondition that min <= max. It was intentionally omitted to avoid hinting at the solution.
