LeetCode 1840 Maximum Building Height | Hard Problem | Easiest Intuition & Step-by-Step Explanation

🔥 LeetCode 1840 - Maximum Building Height (Hard) Complete Explanation in Part 1!

In this video, we break down one of the trickiest weekly contest problems with crystal clear intuition. Learn how to handle huge constraints (n up to 1e9) using critical points, bound propagation (forward + backward passes), and the famous "tent peak" formula.

We derive everything from scratch:
- Why h[1] must be 0
- Slope constraint (|hi-hi+1| less = 1) and its global implication
- Adding endpoints (1,0) and (n, n-1)
- Forward & Backward tightening of upper bounds
- Mathematical derivation of the maximum peak between two points: (A + B + d) / 2

This approach solves the problem in O(m log m) time and is the cleanest greedy + math solution.

Perfect for interview preparation, competitive programming, and understanding 1-Lipschitz constraints.
