Hi! Welcome to Stack Overflow. This question will be closed because asking for tutorials is explicitly off-topic. Please see the [Tour], [ask] and come back with a [mcve] when you've tried something. Also, please never post images of code, post the actual code as text.
To editors and reviewers in-lining images of code, please see Meta: "Would you accept an edit where link images of code are replaced by inline images?" and reject.
Thank you for this code snippet, which may provide some immediate help. A proper explanation would greatly improve its educational value by showing why this is a good solution to the problem, and would make it more useful to future readers with similar, but not identical, questions. Please edit your answer to add explanation, and give an indication of what limitations and assumptions apply.
