Today was another exciting day in my DSA grind! I continued exploring Trees and tackled three diverse problems across LeetCode and GeeksforGeeks, each sharpening different problem-solving dimensions.

✅ Topics Covered:
Binary Tree Right Side View (Trees)

Divisible and Non-divisible Sums Difference (LeetCode POTD)

Print Leaf Nodes from Preorder Traversal of BST (GFG POTD)

🌲 Binary Tree Right Side View:
I explored how to visually capture what you'd see from the right side of a binary tree. The key was performing a level-order traversal and picking the last node at every level. A simple trick, but very effective in transforming perspective-based problems into structured BFS logic.

💡 Divisible and Non-divisible Sums Difference:
This LeetCode POTD challenged me to calculate the difference between the sum of all numbers from 1 to n and twice the sum of those divisible by a number m. Recognizing the mathematical pattern allowed me to solve it using just arithmetic formulas—no loops needed!

🌿 Print Leaf Nodes from Preorder Traversal of BST:
A classic GFG-style logic puzzle: given a preorder traversal, determine which values are leaf nodes in the resulting BST. It tested my understanding of binary search tree construction and recursive depth tracking. A great way to strengthen both recursion and BST intuition.

🔍 Key Learnings:
Perspective-based tree problems can often be reduced to level-wise traversal logic.

Mathematical sum problems become straightforward once you spot the pattern and derive a formula.

Simulating BST construction from traversal orders helps solidify your grasp of tree structure.
