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.

Solution:

s = input()
words = [word for word in s.split(" ")]
print(" ".join(sorted(list(set(words)))))Code language: PHP (php)
