# 0557 - Reverse Words in a String III

[0557 - Reverse Words in a String III](https://leetcode.com/problems/reverse-words-in-a-string-iii/)

Given a string s, reverse the order of characters in each word within a sentence while still preserving whitespace and initial word order.

## Examples

Input: s = "Let's take LeetCode contest" Output: "s'teL ekat edoCteeL tsetnoc"

Input: s = "God Ding" Output: "doG gniD"

## Constraints

1 <= s.length <= 5 \* 104 s contains printable ASCII characters. s does not contain any leading or trailing spaces. There is at least one word in s. All the words in s are separated by a single space.

## Java Solution

```java
class Solution {
    public String reverseWords(String s) {
        StringBuilder sb = new StringBuilder();
        for (String word : s.split(" ")) {
            for (int i = word.length()-1; i > -1; i--) {
                sb.append(word.charAt(i));
            }
            sb.append(' ');
        }
        sb.deleteCharAt(sb.length()-1);
        return sb.toString();
    }
}
```
