Expert Solution

Step 1

Given a string ‘str’, the task is to find whether the vowels in the string are in alphabetical order or not. The string contains only lowercase alphabets.

Examples:

Input: str = "aabbbddeecc"
Output: Vowels are in alphabetical order
The vowel characters in the string are : a, a, e, e 
which are in sorted order.

Input: str = "aabbbdideecc"
Output: Vowels are not in alphabetical order

Approach:

Traverse the array and find the characters which are vowels.
If any vowel is less than the vowel which occurred previously in the array then print Vowels are not in alphabetical order.
Else, print Vowels are in alphabetical order.
