VI🌳 Inorder Traversal Iterative | Binary Tree (Without Recursion)
📌 Traversal Order:
Left → Root → Right (LNR)
Instead of recursion, we use a Stack to simulate the call stack.
🧠 Algorithm Idea:
1️⃣ Push all left nodes into the stack
2️⃣ Pop the top node → Visit it
3️⃣ Move to its right subtree
4️⃣ Repeat until stack is empty
⚡ Time Complexity: O(n)
📦 Space Complexity: O(h) (height of tree)
💡 Important for interviews because it tests your understanding of recursion internally.

CO🔍 Searching in a BST. 👉 Start at the root, compare the value, and go left for smaller or right for larger. ⚡ Every step cuts the search space in half — that’s why BSTs feel fast and clean.

SHThe real test of recursion is not writing it but visualizing how values flow from leaf to root.
LeetCode Problem of the Day Sum of Root To Leaf Binary Numbers
Today’s POTD blends binary interpretation with tree traversal where every root to leaf path forms a binary number and the task is to compute their total sum.
Instead of treating paths as strings we solve it using DFS with recursion carrying the current binary value down the tree and updating it at each node.
At every step:
currentValue = (currentValue << 1) + node.val
When we reach a leaf node we add the accumulated value to the final result.
Key focus areas:
Depth First Search traversal
Recursion with state propagation
Binary number construction
Bit shifting logic
Tree path aggregation
This problem strengthens your understanding of how recursive state flows in tree structures while combining bit manipulation with traversal logic a pattern frequently tested in coding interviews to evaluate clarity of recursion thinking.

DATree Traversals: The one concept that trips up every CS student 🌳
Three ways to visit every node. Same tree. Different order. The only question: When do you visit the root?
PRE = before (root first)
IN = between (root middle)
POST = after (root last)

KOEver seen a Python list that contains itself? In this clip I walk through a classic recursive‑structure example:
By assigning the list to its own first element, you create a self‑referential loop: "a" doesn’t expand forever, it just points back to the same object in memory. This is a great way to understand Python’s object model, references, and how mutable data structures behave under the hood. It also shows why printing a recursive list gives you [...] instead of an infinite dump. Perfect little brain teaser for anyone learning Python, data structures, or exploring how references actually work in dynamic languages!
