/**
 * 557. Reverse Words in a String III
 *
 * 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.

 Example 1:
 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.
