Remove Duplicates and Count Vowels | Dataford Interview Questions

Write a Python program to remove duplicates from a list and to count the number of vowels in a given string. Preserve the order of each value's first occurrence, and treat a, e, i, o, u, and y as vowels regardless of case. Implement def process_data(items, text):, returning [unique_items, vowel_count].

Constraints

0 <= len(text) <= 10^5
List values are hashable
Vowels are the letters a, e, i, o, u, and y, counted without regard to case
