Binary Tree Level Order Traversal
đ Problem
Given a binary tree, print its nodes level by level (top to bottom, left to right within each level).
đ§ Approach
This is a classic Breadth-First Search (BFS) problem â use a queue. Start by pushing the root. Then repeatedly: pop a node, print it, and push its left and right children (if they exist) into the queue. This naturally processes the tree level by level.
