Practice Evaluate Boolean Binary Tree
Read the task, work through the examples, and check your approach against the constraints. Use the original LeetCode task for coding and submissions.
Problem Statement
In the full binary tree, each node has either zero or two children. Leaf values 0 and 1 mean false and true. Internal value 2 means OR and 3 means AND. Recursively evaluate both children and apply the internal node's operator. Return the boolean value of the root.
