Understanding the Count Vowel Substrings of a String Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
A substring is a contiguous (non-empty) sequence of characters within a string. A vowel substring is a substring that only consists of vowels ('a', 'e', 'i', 'o', and 'u') and has all five vowels present in it. Given a string word, return the number of vowel substrings in word.

Examples
word = "aeiouu"2The vowel substrings of word are as follows (underlined): - "aeiouu" - "aeiouu"
word = "unicornarihan"0Not all 5 vowels are present, so there are no vowel substrings.
word = "cuaieuouac"7The vowel substrings of word are as follows (underlined): - "cuaieuouac" - "cuaieuouac" - "cuaieuouac" - "cuaieuouac" - "cuaieuouac" - "cuaieuouac" - "cuaieuouac"
Constraints
1 <= word.length <= 100word consists of lowercase English letters only.How Interview Coder Helps with Leetcode Problems
