LeetCode 112 🚀 Clean Recursive Path Sum

Solved LeetCode #112 – Path Sum using the optimized recursive subtraction approach in JavaScript 🌳🔥
💡 Smart Trick: Instead of carrying the running sum,
we subtract the current node value from targetSum while traversing.
Base Case:
If we reach a leaf node
Check if root.val === targetSum
Recursive Step:
Call left and right subtree with
targetSum - root.val
Return left || right
This pattern teaches:
Clean recursion
Divide & conquer thinking
Efficient root-to-leaf traversal
Interview-ready tree logic
Master this and many tree problems become easier 🚀
