CODid you know that Java behaves differently when comparing wrapper classes like Integer? 🤯
In this quiz, we test a simple line of code:
Integer a = 128;
Integer b = 128;
System.out.println(a == b);
Most beginners expect true, but the correct output is: ❌
👇 Watch the video to learn why Java outputs false here!
This happens because of Integer caching mechanism in Java — only values between -128 to 127 are cached. Anything outside that range creates a new object, so == compares references, not values. 🧠💡

🎯 You'll Learn:
✔ Java wrapper class behavior
✔ Integer caching
✔ Difference between == and .equals()
✔ Common Java interview question

Did you get it right? 😎

GHA Binary Tree Data Structure is a hierarchical data structure in which each node has at most two children, referred to as the left child and the right child. It is commonly used in computer science for efficient storage and retrieval of data, with various operations such as insertion, deletion, and traversal.

Binary Trees can be traversed in various ways, one of which is Inorder traversal.
In this type of traversal, we proceed as follows:
- Traverse the left subtree
- Visit the root node
- Traverse the right subtree.
The traversal can also be reversed - from right to root to left.
Basic Operations on Binary Tree:
Tree Traversals (Inorder, Preorder and Postorder)
Level Order Tree Traversal
Find the Maximum Depth or Height of given Binary Tree
Insertion in a Binary Tree
Deletion in a Binary Tree
Enumeration of Binary Trees
Some other important Binary Tree Traversals :
Level order traversal in spiral form
Reverse Level Order Traversal
BFS vs DFS for Binary Tree
Inorder Tree Traversal without Recursion
Morris traversal for Preorder
Iterative Preorder Traversal
Iterative Postorder Traversal Using Two Stacks
Diagonal Traversal of Binary Tree
Boundary Traversal of binary tree
