Given a string, you need to reverse the order of characters in each word within a sentence while still preserving whitespace and initial word order.
Input: "Let's take LeetCode contest" Output: "s'teL ekat edoCteeL tsetnoc"
Note: In the string, each word is separated by single space and there will not be any extra space in the string.
Reverse each word and then combine to a sentence.
class Solution: def reverseWords(self, s: str) -> str: words = s.split() reversed_words =  for word in words: reversed_words.append(word[::-1]) return " ".join(reversed_words)
