3. Prepare a flowchart that describes going to the library to study for an exam. Your flowchart should include these items: finding a place at the library to study; checking to see if you have your book, paper, highlighter, and so forth; traveling to the library; and the possibility of moving to another location if the place you chose to study starts to get crowded.
