Question 10
Level 2

Question:
Write a program that accepts a sequence of whitespace separated words as input and prints the words after removing all duplicate words and sorting them alphanumerically.
Suppose the following input is supplied to the program:
hello world and practice makes perfect and hello world again
Then, the output should be:
again and hello makes perfect practice world

Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
We use set container to remove duplicated data automatically and then use sorted() to sort the data.
'''

input_str = input(
    'enter the sentence to remove the duplicates and sort them alphabettically: ')

inputSet = set(input_str.strip().split(' '))

result = sorted(inputSet)
print(result)
