What changes are you trying to make? (e.g. Adding or removing code, refactoring existing code, adding reports)

In this pull request, I am adding functionality to an existing anagram_checker function. Specifically, I am implementing two main features:

1. Base Anagram Checker: A function that determines if two strings are anagrams of each other, ignoring case sensitivity.
2. Expanded Functionality: An enhancement that adds a boolean parameter is_case_sensitive to the function. This parameter allows the function to handle case sensitivity based on user input.

What did you learn from the changes you have made?

I have learned that incorporating case sensitivity into an anagram checker can be achieved by adjusting the string normalization process based on a parameter. This change allows the function to be more flexible and adaptable to different use cases. The approach to solving the problem involves basic string manipulation techniques, including converting to lowercase, sorting, and comparing.

Was there another approach you were thinking about making? If so, what approach(es) were you thinking of?

Initially, I considered using a different method to check for anagrams that involved counting character frequencies rather than sorting. While counting characters is efficient in some cases, sorting provides a straightforward and effective solution for this problem and ensures that the solution remains easy to understand and implement.
