    226 - Invert Binary Tree.

    Easy

    Given the root of a binary tree, invert the tree, and return its root.

    Example 1:

    Input: root = [4,2,7,1,3,6,9]

    Example 2:

    Input: root = [2,1,3]

    Output: [2,3,1]

    Example 3:

    Input: root = []

    Output: []

    Constraints:

    • The number of nodes in the tree is in the range [0, 100].
