Input Format: A string of random letter characters (no numbers or other buttons were pressed). Output Format: A string that says 'Deja Vu' if any letter is repeated in the input string, or a string that says 'Unique' if there are no repeats. Sample Input: aaaaaaaghhhhjkll Sample Output: Deja Vu Explanation: Your program should output 'Deja Vu' because there are many repetitions in 'aaaaaaaghhhhjkll'. a = input() b = list(a) temp =  con = False for i in b: if i in temp : print('Deja Vu') con = True else: temp.append(i) if con == False : print('Unique') else : pass
