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.

public class Solution { public String reverseWords(String s) { if(s.length() == 0) return s; String[] words = s.split(" "); StringBuffer sb = new StringBuffer(""); for(String word : words){ for(int i = word.length() - 1 ;i >= 0; i --) sb.append(word.charAt(i)); sb.append(" "); } sb.setLength(sb.length() - 1); return
