Univalue Tree is an example of Tree problems. In this post we will see how we can solve in Javascript.

Problem Description

Given a binary tree, check if it's uni-value tree. A Uni-value tree means all nodes of the tree have the same value.

For example: Given binary tree,

          5

         / \

        5   5

       / \   \

      5   5   5

return true.

Please check the main.js snippet for the solution.
