    1456 - Maximum Number of Vowels in a Substring of Given Length\.

    Medium

    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:

    • <code>1 <= s.length <= 10<sup>5</sup></code>

    • s consists of lowercase English letters.

    • 1 &lt;= k &lt;= s.length
