###Input format:

The second line gives $$n $$positive integer and $$I $$integer $$X_ I $$represents the amount of note $$I $.
###Output format:
In one line, output the corresponding amount for each note, if there is no note with the same amount before; Otherwise output$$*$$
Note that the two outputs are separated by spaces in the middle and no spaces at the end of the line
