WebLeetCode 226. Invert Binary Tree 翻转二叉树（Java） 题目： Invert a binary tree. Trivia: This problem was inspired by this original tweet by Max Howell: Google: 90% of our engineers use the software you wrote (Homebrew), but you can’t invert a binary tree on a whiteboard so f*** off. Webas LCA(\(u,v\)), is the lowest node in the tree that is both an ancestor of \( u \) and an ancestor of \( v \). See the following diagram The blue vertex is the LCA of the yellow vertices. Warmup -- A slow algorithm To get warmed up, let's start with a naive algorithm for computing LCAs.
