Input : arr[] = {12, 10, 5, 6, 52, 36}
            k = 2
Output : arr[] = {5, 6, 52, 36, 12, 10}
Explanation : Split from index 2 and first 
part {12, 10} add to the end .

Input : arr[] = {3, 1, 2}

        int position = 2;
  
        splitArr(arr, 6, position);
  
        for (int i = 0; i < n; ++i)
            System.out.print(arr[i] + " ");
