Answer the follwoing question regarding java:
![Fill in the code to complete the following method for binary search.
public static int recursive BinarySearch(int[] list, int key) {
int low = 0;
int high list.length - 1;
return
}
public static int recursive BinarySearch(int[] list, int key,
int low, int high) {
if (low > high) // The list has been exhausted without a match
return -low - 1; // Return -insertion point - 1
int mid= (low + high) / 2;
if (key < list[mid])
return recursive BinarySearch(list, key, low, mid - 1);
else if (key == list[mid])
return mid;
else
return recursive BinarySearch(list, key, mid + 1, high);
}
