Question

program to print all the unique characters in a given sentence

Answer 1

Co‎de: [in Python language]

$\tt s\ =\ in put("Enter\ a\ sentence:\ ")\\l\ =\ list()\\for\ i\ in\ s:\\{\ \ \ \ \ }if\ s.count(i)\ ==\ 1:\\{\ \ \ \ \ }{\ \ \ \ \ }l.append(i)\\print()\\print("The\ unique\ characters\ in\ the\ sentence\ are:\ ")\\for\ i\ in\ l:\\{\ \ \ \ \ }print(i)$

Explanation:

We retrieve the sentence using the $\tt in put()$ function and store it into a variable 's'. A list is created to store the unique characters in the sentence. A $\tt for$ loop is initiated to traverse through the characters in the sentence, which also checks if it's unique or not through a conditional statement that checks if its count/occurrence is equal to 1, using the $\tt count()$ method. If it is, it gets added to the list earlier created for the same and the characters are later on printed.
