LeetCode 2785. Sort Vowels in a String
Given a?0-indexed?string?s
,?permute?s
?to get a new string?t
?such that:
All consonants remain in their original places. More formally, if there is an index?
i
?with?0 <= i < s.length
?such that?s[i]
?is a consonant, then?t[i] = s[i]
.The vowels must be sorted in the?nondecreasing?order of their?ASCII?values. More formally, for pairs of indices?
i
,?j
?with?0 <= i < j < s.length
?such that?s[i]
?and?s[j]
?are vowels, then?t[i]
?must not have a higher ASCII value than?t[j]
.
Return?the resulting string.
The vowels are?'a'
,?'e'
,?'i'
,?'o'
, and?'u'
, and they can appear in lowercase or uppercase. Consonants comprise all letters that are not vowels.
?
Example 1:
Input: s = "lEetcOde"
Output: "lEOtcede"
Explanation: 'E', 'O', and 'e' are the vowels in s; 'l', 't', 'c', and 'd' are all consonants. The vowels are sorted according to their ASCII values, and the consonants remain in the same places.
Example 2:
Input: s = "lYmpH"
Output: "lYmpH"
Explanation: There are no vowels in s (all characters in s are consonants), so we return "lYmpH".
?
Constraints:
1 <= s.length <= 105
s
?consists only of letters of the?English alphabet?in?uppercase and lowercase.
--------------------------------------
給定一個索引為 0 的字符串 s,對 s 進(jìn)行排列以獲得新字符串 t,使得:
所有輔音都保留在原來的位置。 更正式地說,如果存在一個索引 i 且 0 <= i < s.length 且 s[i] 是輔音,則 t[i] = s[i]。
元音必須按照其 ASCII 值的非遞減順序排序。 更正式地說,對于索引 i、j 對,其中 0 <= i < j < s.length,使得 s[i] 和 s[j] 是元音,則 t[i] 的 ASCII 值不得高于 t[j]。
返回結(jié)果字符串。
元音為“a”、“e”、“i”、“o”和“u”,它們可以小寫或大寫形式出現(xiàn)。 輔音包括所有非元音的字母。
