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.
\n
Example 1:
\n\nInput: word = "aeioqq", k = 1
\n\nOutput: 0
\n\nExplanation:
\n\nThere is no substring with every vowel.
\nExample 2:
\n\nInput: word = "aeiou", k = 0
\n\nOutput: 1
\n\nExplanation:
\n\nThe only substring with every vowel and zero consonants is word[0..4], which is "aeiou".
Example 3:
\n\nInput: word = "ieaouqqieaouqq", k = 1
\n\nOutput: 3
\n\nExplanation:
\n\nThe substrings with every vowel and one consonant are:
\n\nword[0..5], which is "ieaouq".word[6..11], which is "qieaou".word[7..12], which is "ieaouq".\n
Constraints:
\n\n5 <= word.length <= 2 * 105word consists only of lowercase English letters.0 <= k <= word.length - 5r, find the maximum l such that both conditions are satisfied using binary search."
