Hash Table
String
Sliding Window
You are given a string word and a non-negative integer k.
Return the total number of substrings of word that contain every vowel ('a', 'e', 'i', 'o', and 'u') at least once and exactly k consonants.
Examples
Example 1
Input: word = "aeioqq", k = 1
Output: 0
Explanation:
There is no substring with every vowel.
Example 2
Input: word = "aeiou", k = 0
Output: 1
Explanation:
The only substring with every vowel and zero consonants is word[0..4] , which is "aeiou" .
Example 3
Input: word = " ieaouqqieaouqq ", k = 1
Output: 3
Explanation:
The substrings with every vowel and one consonant are:
Constraints
5 <= word.length <= 250
word consists only of lowercase English letters.
0 <= k <= word.length - 5
