Level Order Traversal (Breadth First Search or BFS) of Binary Tree - GeeksforGeeks

Sushant Kumbhar on Instagram: "Best Data Structure: Balanced BST (AVL Tree / Red-Black Tree) or TreeMap/TreeSet in Java Reasons: 1. Maintains Sorted Order Automatically – No need to sort after every insertion (unlike ArrayList/LinkedList). 2.

Scalable for Large Data – Handles thousands/millions of records while keeping them
