I am sorry for involving the use of AI in this post. Most of the parts in the post were originally written by me while for some parts, I employed the use of AI to help make my tenses more formal and to make some corrections... I have gone through the terms and conditions and I have seen AI-generated contents are frowned at... I sincerely apologize and I promise to post original contents henceforth and dissociate myself from the use of AI for my posts and comments. Thanks, as you consider my apology.
