Smooth Occlusion (AtCoder F) | Advanced Binary Search + Interval Constraints

Описание: In this video, we solve “Smooth Occlusion” from AtCoder — a beautiful real-world inspired problem that blends binary search with interval feasibility.

🦷 Given pairs of upper and lower teeth, we can grind each tooth to adjust their height at a cost. We want to make all tooth pairs sum to the same height `H`, and ensure smoothness across adjacent teeth.

We cover:
How to model the problem using Binary Search on Answer
How to use interval propagation to check feasibility
Efficient cost calculation and optimization
