AP Computer Science Principles taught interactively

The Student and Tutor worked through a Unix file management assignment, practicing directory creation using `mkdir` and file editing with the `vi` editor. They also resolved a Java programming error related to conditional statements for identifying even numbers. The plan is to continue with the remaining Unix assignment questions and further Java practice in the next session.

The Tutor and Student reviewed linked list operations, traversal algorithms, and insertion sort for linked lists. The Student then spent significant time implementing and debugging `push` and `pop` methods for a `PlaneQueue` class in Python, simulating an air traffic control queue. The next session will cover Java.

The session focused on Python programming, guiding the Student through solving a problem involving `for` loops and `if-elif-else` conditions with the modulus operator. The Student also learned the distinction between `print` and `return` statements in functions and practiced building `add`, `subtract`, and `divide` functions, incorporating conditional logic to handle number order. These functions will be utilized for a future calculator application, and additional homework on `if` conditions and `for` loops was assigned.

Student and Tutor engaged in an extensive practice session on fundamental data structure operations. They started with singly linked list removal and search algorithms, then moved to understanding and applying append and prepend operations on doubly linked lists. The session involved numerous exercises to track list changes and pointer updates, concluding with plans to continue in the next class.

The Student and Tutor practiced Java programming by solving problems related to integer input, incremental output, and array reversal. Subsequently, they moved on to Data Structures, learning about the List Abstract Data Type and the mechanics of Singly Linked Lists, including append, prepend, and insert after operations. The session concluded with plans to continue the discussion the following day.

Student and Tutor collaborated on an academic assignment researching job opportunities in cloud computing, specifically an AWS engineer role. They focused on refining the essay's content, discussing strategies for referencing and managing technical detail, and identifying official AWS websites as appropriate sources. The student needs to complete the essay for submission.
