WebGiven the root of a binary tree, invert the tree, and return its root.. Example 1: Input: root = [4,2,7,1,3,6,9] Output: [4,7,2,9,6,3,1] Example 2: Input: root = [2,1 ... WebTree. A connected acyclic graph is called a tree. In other words, a connected graph with no cycles is called a tree. The edges of a tree are known as branches. Elements of trees are called their nodes. The nodes without child nodes are called leaf nodes. A tree with ‘n’ vertices has ‘n-1’ edges.
