The student's solution is incomplete. The binarySearch method has no implementation - it only contains a comment indicating where code should be written. The method needs to:

1. Implement the actual binary search algorithm
2. Calculate the middle index
3. Compare the middle element with the target value
4. Recursively or iteratively search the appropriate half
5. Handle the base case when the search space is exhausted

A proper implementation would look something like:

int binarySearch(int arr[], int l, int r, int x) {
    if (r >= l) {
        int mid = l + (r - l) / 2;
        if (arr[mid] == x) return mid;
        if (arr[mid] > x) return binarySearch(arr, l, mid - 1, x);
        return binarySearch(arr, mid + 1, r, x);
    }
    return -1;
}
