    # Definition for a binary tree node.
    # class TreeNode(object):
    #     def __init__(self, x):
    #         self.val = x
    #         self.left = None
    #         self.right = None
    class Solution(object):
        def inorderTraversal(self, root):
            :type root: TreeNode
            :rtype: List[int]
            return self.inorderTraversal(root.left) + [root.val] + self.inorderTraversal(root.right) if root is not None else []
