Binary Tree Cameras

Explore how to apply dynamic programming to optimize camera placement in a binary tree. Learn to calculate the minimum number of cameras needed to monitor all nodes by leveraging subproblem solutions and logical problem analysis.

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 ...
