static void selectionSort(String arr_items[],int n)
{
   
    for(int i = 0; i < n - 1; i++)
    {
     
       
        int min_index = i;
        String minStr = arr_items[i];
        for(int j = i + 1; j < n; j++)
        {
             
            if(arr_items[j].compareTo(minStr) < 0)
            {

                min_index = j;
            }
        }

    {
        String temp = arr_items[min_index];
        arr_items[min_index] = arr_items[i];
        arr_items[i] = temp;
    }
    }
}
