🌟 Day 222/∞ 🚀 Solved Binary Tree Right Side View 🌳➡️ 🧩 Implemented both BFS (level order traversal) and DFS (right-first recursion) to capture the visible nodes from the right. TC: O(n) | Space: O(h) 💪 #LeetCode #DSA #BinaryTree #BFS #DFS #CodeEveryday #KeepCoding
Day 64 of DSA 🌳 Today I learned Preorder, Inorder, and Postorder Tree Traversals using recursion. It’s amazing how just a few lines of code can perform such magical operations on a tree — absolutely mind-blowing! ⚡🔥 #DSA #BinaryTree #Recursion #CodingJourney #100DaysOfCode
