{ "data": { "question": { "questionId": "345", "questionFrontendId": "345", "categoryTitle": "Algorithms", "boundTopicId": 1509, "title": "Reverse Vowels of a String", "titleSlug": "reverse-vowels-of-a-string", "content": "
Given a string s, reverse only all the vowels in the string and return it.
The vowels are 'a', 'e', 'i', 'o', and 'u', and they can appear in both lower and upper cases, more than once.
\n
Example 1:
\n\nInput: s = "IceCreAm"
\n\nOutput: "AceCreIm"
\n\nExplanation:
\n\nThe vowels in s are ['I', 'e', 'e', 'A']. On reversing the vowels, s becomes "AceCreIm".
Example 2:
\n\nInput: s = "leetcode"
\n\nOutput: "leotcede"
\n\n
Constraints:
\n\n1 <= s.length <= 3 * 105s consist of printable ASCII characters.给你一个字符串 s ,仅反转字符串中的所有元音字母,并返回结果字符串。
元音字母包括 'a'、'e'、'i'、'o'、'u',且可能以大小写两种形式出现不止一次。
\n\n
示例 1:
\n\n输入:s = \"IceCreAm\"
\n\n输出:\"AceCreIm\"
\n\n解释:
\n\ns 中的元音是 ['I', 'e', 'e', 'A']。反转这些元音,s 变为 \"AceCreIm\".
示例 2:
\n\n输入:s = \"leetcode\"
\n\n输出:\"leotcede\"
\n\n\n
提示:
\n\n1 <= s.length <= 3 * 105s 由 可打印的 ASCII 字符组成\\u7248\\u672c\\uff1a \\u7f16\\u8bd1\\u65f6\\uff0c\\u5c06\\u4f1a\\u91c7\\u7528
