I have to use the app PROCESSING exclusively, Again there is only PROCESSING language in this answer

Download the lab13_data_in.txt file In your sketch, read this file using loadStrings() Remember, strings are case sensitive! Based on this file, write code in your sketch to answer the following questions. Hint, there is one element in the array at this point. Does the text processing exist in the file? What is numeric position in the string of the first occurrence of literacy What is the length of the string? What is the character at the middle of the string? What is the substring of 10 characters from the middle? Split the string, with the delimiter "." Append your name the end of the newly formed string array. In your sketch write the file using saveStrings() with the filename lab13_data_out.txt Feel free to use any temporary variables you may need, such as the length of the string

When printing your answers from the sketch, make sure you are using descriptive messaging, and not just printing an answer by itself.

this is what lab13_data_in_txt looks like "Processing is a flexible software sketchbook and a language for learning how to code within the context of the visual arts. Since 2001, Processing has promoted software literacy within the visual arts and visual literacy within technology. There are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning and prototyping. This was quoted from the Processing.org website."

any help will be appreciated
