+# 557. Reverse Words in a String III
+
+### 2017-04-09
+
+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.
+
+
+
+# Solution
+
+```swift
+class Solution {
+    func reverseWords(_ s: String) -> String {
+        return s.components(separatedBy: " ")
+            .flatMap({ $0.characters.reversed().reduce("", { $0 + $1.description})})
+            .reduce("", { $0.isEmpty ? $1 : "\($0) \($1)" })
+
+    }
+}
+```
