AVL Trees Complete Guide: Rotations, Balance Factor & Insertions | AP CS Data Structures

In this AP Computer Science Data Structures lesson, I give a complete guide to AVL Trees — including rotations, balance factor, insertions, and how to detect imbalance step by step. If you understand Binary Search Trees but struggle with self-balancing trees, this video will connect everything clearly. I explain not just what happens during rotations, but why they are necessary and how to recognize each case instantly. In this video, I cover: • What an AVL tree is and why we need it • The balance factor and how to calculate it • How to detect imbalance in a tree • The four rotation cases (LL, RR, LR, RL) • Step-by-step insertion with rotations • Time complexity and why AVL trees guarantee O(log n) operations • Common mistakes students make on exams This is perfect for AP CSA students learning advanced tree structures or preparing for tests involving BSTs and self-balancing trees. If you want a deep, structured understanding of AVL trees in Java, this lesson will give you both the conceptual clarity and exam-level confidence you need. #APComputerScience #APCSA #DataStructures #AVLTree #BinarySearchTree #BST #TreeRotations #BalanceFactor #Recursion #JavaProgramming #APCSExamPrep #ComputerScience #CodingInterviewPrep #STEMEducation #HighSchoolCS
