链接 557. Reverse Words in a String III

题目

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

题解

暴力写，没啥好说的

class Solution:
    def reverseWords(self, s: str) -> str:
        results = []
        temp = ""
        result = ""
        for i in range(len(s) - 1, -1, -1):
            if s[i] != " ":
                temp += s[i]
            else:
                result = temp + " " + result
                temp = ""
        result = temp + " " + result
        return result.rstrip(" ")

不考虑重复遍历的话，一行流也行

class Solution:
    def reverseWords(self, s: str) -> str:
        return " ".join(word[::-1] for word in s.split())
