Reverse Words in a String III | Leetcode problem No. 556 | String

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

Example 1:

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

Example 2:

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

Constraints:

• 1 <= s.length <= 5 * 10<sup>4</sup>

• 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.

class Solution {
    public String reverseWords(String s) {
        return Arrays.stream(s.split(" "))
                .map(str -> new StringBuilder(str).reverse())
                .collect(Collectors.joining(" "));
    }
}
