Solution: Univalued Binary Tree

Explore how to verify if a binary tree is uni-valued by performing a depth-first search traversal. Learn the recursive checks at each node comparing values with children, and understand the algorithm's time and space complexities. This lesson helps develop your skills to solve similar tree problems efficiently in Go.

We'll cover the following...

Statement

A binary tree is considered uni-valued if every node in the tree contains the same value.

Given the root of a binary tree, return TRUE if the tree is uni-valued, or FALSE otherwise.

Constraints:

  • The number of nodes in the tree is in the range [1,100][1, 100].

  • 0≤0 \leq ...
