To solve this, we will follow these steps ret := 0, define two maps m and cnt, set m ["00000"] := -1 store vowels into vowels array for i in range 0 to size of s x := s [i], and ok := false increase cnt [x] by 1, set temp := empty string for k in range 0 to 4: temp := temp + '0' + cnt [vowels [k]] mod 2 What makes this a O(n) is that once we have checked for the vowel substring s[2] to s[3] i.e) oi we can be sure that this vowel substring need not be considered further in any of the vowel substring that may come later as there is a non vowel character after this thus making any substring includes this substring to not be a vowel substring. For every substring, it invokes the has_k_distinct_vowels function to validate if the substring has exactly k unique vowels.
