Binary Tree Cameras

Explore how to install the fewest cameras on a binary tree to monitor all nodes effectively. This lesson uses dynamic programming to optimize camera placement, helping you develop efficient solutions for complex tree monitoring problems.

We'll cover the following...

Statement

You are given the root of a binary tree. Cameras can be installed on any node, and each camera can monitor itself, its parent, and its immediate children.

Your task is to determine the minimum number of cameras required to monitor every node in the tree.

Constraints:

  • The number of nodes in the ...
