Dear all,
I have
A={
'12/08' ' ' '01/09' ' ' '02/09' ' ' '03/09' ' ' '03/09' ' ' '04/09' ' ' '05/09' ' ' '06/09' ' ' '07/09' ' ' '08/09' ' ' '09/09' ' ' '10/09' ' ' '11/09' ' ' '12/09' ' ' '01/10' '33 ' '01/10' '55 ' '02/10' ' ' '03/10' ' ' '04/10' ' ' '05/10' ' ' '06/10' ' ' '07/10' ' ' '08/10' ' ' '09/10' ' ' '10/10' ' ' '11/10' ' ' '12/10' ' ' '01/11' '123 ' '01/11' ' 321' '02/11' ' ' '03/11' ' ' '04/11' ' ' '05/11' ' ' '06/11' ' ' '07/11' ' ' '08/11' ' ' '09/11' ' ' '10/11' ' ' '11/11' ' '}
I want to erase the second duplicate so as to have
