How to get recursion questions right every time (AP CSA)
Recursion exam questions can give any computer science student a headache. This video uses one SIMPLE BUT RELIABLE technique to solve five example recursion questions, each with increasing complexity.
These MCQs/multiple choice questions are from the AP CSA exam in Java, but the same idea 100% works for C, C++, Python, Javascript, C#, or any other programming language you might be studying.
Recursion is commonly taught in introductory coding courses such as AP Computer Science A, basic Java or Python, data structures courses, and algorithms courses.
I'm a private computer science tutor with a bachelor's degree in Computer Science from UT Austin as well as a master's degree in computer science. I'm also a certified teacher, and I love helping students score higher on CS exams and understand code at a deeper level.
