Imagine a grocery store that has various items for sale. Each item is uniquely identified by a string name. However, due to some limitations in the store's inventory system, sometimes the same item gets entered more than once in the list of available items. Your task is to write a Python program that takes a list of item names and counts the unique items in it. Your program should then return a dictionary where the keys are the unique item names and the values are the counts of those items in the list. For example: If the input list is ["apple", "banana", "apple", "orange", "banana", "apple"], the output should be {'apple': 3, "banana": 2, 'orange": 1}. Requirements: Your program should be written in Python. You should not use any third-party libraries. Input: A list of n (1 <= n <= 10^5) string elements, where each string represents the name of an item in the grocery list. Output: A dictionary with keys as unique item names and values as their counts in the list.
