Shuffle an array in a specific format : I need to shuffle an array in such a way that in each shuffle third element of the array should change to the first one
   
      For Eg :
        My array is array(1,2,3,4,5,6,7,8,9);
       in first shuffle I want the array to array(4,5,6,7,8,9,1,2,3) 
       next array(7,8,9,1,2,3,4,5,6) and so on...

      Hope any one will help me

        Thanks in advance !
