AVL Tree Questions

• AVL tree questions are explained here in this tutorial with solution.
• AVL Tree questions are generally asked in GATE CSE exam and also in UGC NET exam.
• AVL tree questions and answers explained in tutorial are also asked in previous year Data Structure Subject of AKTU examination.
• AVL practice problems discussed in this tutorial will be helpful to students to prepare for GATE exam.

AVL Tree Insertion Questions

• AVL tree insertion questions are discussed here in this section.
• In AVL tree Node is inserted according to Binary Search Tree Insertion Logic.
• In AVL Tree after inserting a node if Balance Factor of a node becomes 2 or -2 then we perform suitable AVL Tree Rotation to make the tree Balanced.

Questions based on AVL Tree Insertion are given here with solution. you can see the following figures to see the questions with solution.

AVL Tree Deletion Questions

• In AVL Tree a Node is deleted according to Binary Search Tree Deletion Logic.
• In AVL Tree after inserting a node if Balance Factor of a node becomes 2 or -2 then we perform suitable AVL Tree Rotation to make the tree Balanced.

Example of deletion in AVL tree is given here

Construct an AVL tree Questions

Most of the time questions are asked in GATE CSE exam to construct the AVL from given sequence of keys or alphabet.

In this section we will discuss some questions to construct AVL tree from given sequence of numbers of alphabet.

Questions 1 . What will be resultant AVL Tree when we Insert 10, 6, 11, 12, 1, 7, 0, 2, 3.

Questions 2 . Construct the AVL tree from the following keys B, C, G, E, F,  D,  A.

Question 3 – Construct the AVL tree for the following Sequence

1 , 2,  3 , 4,  8,  7 , 6,  5,  11,  10,  12

Solution of above question 1 , 2 and 3 is explained here in the given picture.

Conclusion and Summary

In this tutorial we have explained the AVL tree insertion and AVL tree construction based problems. After reading this tutorial students can solve AVL tree based problems.
