Given a 0-indexed string s
, permute s
to get a new string t
such that:
i
with 0 <= i < s.length
such that s[i]
is a consonant, then t[i] = s[i]
.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.
