Problem Statement of Maximum Number of Vowels in a Substring of Given Length

Given a string s and an integer k, return the maximum number of vowel letters in any substring of s with length k.
Vowel letters in English are ‘a’, ‘e’, ‘i’, ‘o’, and ‘u’.

Example 1:

Input: s = “abciiidef”, k = 3
Output: 3
Explanation: The substring “iii” contains 3 vowel letters.

Example 2:

Input: s = “aeiou”, k = 2
Output: 2
Explanation: Any substring of length 2 contains 2 vowels.

Example 3:

Input: s = “leetcode”, k = 3
Output: 2
Explanation: “lee”, “eet” and “ode” contain 2 vowels.

Constraints:

1 <= s.length <= 105
s consists of lowercase English letters.
1 <= k <= s.length

class Solution:
  def maxVowels(self, s: str, k: int) -> int:
    ans = 0
    mx = 0
    kVowels = 'aeiou'

    for i, c in enumerate(s):
      if c in kVowels:
        mx += 1
      if i >= k and s[i - k] in kVowels:
        mx -= 1
      ans = max(ans, mx)

    return ans
