Solving Lowest Common Ancestor of Deepest Leaves in go. Please try yourself first to solve the problem and submit your implementation to LeetCode before looking into solution.

Problem Description

Given a rooted binary tree, return the lowest common ancestor of its deepest leaves.

Recall that:

Example 1:

Input: root = [1,2,3]
Output: [1,2,3]
The deepest leaves are the nodes with values 2 and 3.
The lowest common ancestor of these leaves is the node with value 1.
The answer returned is a TreeNode object (not an array) with serialization "[1,2,3]".

Example 2:

Input: root = [1,2,3,4]
Output: [4]

Example 3:

Input: root = [1,2,3,4,5]
Output: [2,4,5]


  • The given tree will have between 1 and 1000 nodes.
  • Each node of the tree will have a distinct value between 1 and 1000.
