Mid/SeniorSortingString

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
Inputs = "lEetcOde"
Output"lEOtcede"
'E', 'O', and 'e' are the vowels in s; the vowels are sorted by ASCII value while consonants remain in the same places.
Example 2
Inputs = "lYmpH"
Output"lYmpH"
There are no vowels in s, so the string is returned unchanged.

Constraints

  • 1 <= s.length <= 10^5
  • s consists only of letters of the English alphabet in uppercase and lowercase.
