[checkIO]Element 09.Correct Sentence

For the input of your function, you will be given one sentence. You have to return a corrected version, that starts with a capital letter and ends with a period (dot).

Pay attention to the fact that not all of the fixes are necessary. If a sentence already ends with a period (dot), then adding another one will be a mistake.

 

Input: A string.

Output: A string.

 

Example:

correct_sentence("greetings, friends") == "Greetings, friends."

correct_sentence("Greetings, friends") == "Greetings, friends."

correct_sentence("Greetings, friends.") == "Greetings, friends."

 

* 앞 글자가 소문자면 대문자로 바꿔야하고 마지막에 .(온점)을 찍어야한다.

* 앞 글자 이외에 다른 글자는 바꾸면 안됨.
