Is There Another Easy Solution?#2

Question

If you are given a string of random letters, your task is to evaluate whether any letter is repeated in the string or if you only hit unique keys while you typing.

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.

Answer 1

HASAN IMTIAZ ,

you are on the right way by using a set.

> a set can *not* have duplicated characters. so if duplicated characters occur, they will be removed automatically during the creation of the set.

> what about using the *complete string* and make it a set.
> than compare the length (number of characters) from the set with the length of the input string.
> if length equals, there has been no duplicated characters in the input string.
> if the length differs, the input string contains duplicated characters.

Answer 2

text = input()
repeat = set()
condition = False

for char in text:
if char in repeat:
condition = True
repeat.add(char)

if condition:
print("Deja Vu")
else:
print("Unique")

Did your answer work?
Also, if the condition is true, why continue to search the rest and not break the for loop?
