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:**

**Note:** In the string, each word is separated by single space and there will not be any extra space in the string.

classSolution {

funcreverseWords(_s:String)->String {

return s.components(separatedBy:"")

.flatMap({$0.characters.reversed().reduce("", {$0+$1.description})})

.reduce("", {$0.isEmpty?$1:"\($0)\($1)" })

}

}
