The question is a little complex. The problem here is to get rid of duplicates and save the unique elements of array into another array with their original sequence.

For example :

If the input is entered b a c a d t

The result should be : b a c d t in the exact state that the input entered.

So, for sorting the array then checking couldn't work since I lost the original sequence. I was advised to use array of indices but I don't know how to do. So what is your advise to do that?
