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.
func reverseWords(_ s: String) -> String {
let arr = s.components(separatedBy: " ")
print(arr)
var str = ""
for (index, t) in arr.enumerated() {
str.append(reverseStr(t))
if index < arr.count-1 {
str.append(" ")
}
}
return str
}
func reverseStr(_ s: String) -> String {
var str = ""
for c in s.characters.reversed() {
str.append(c)
}
return str
}
