Example 1:

\n\"\"\n
\nInput: root = [10,5,15,3,7,null,18], low = 7, high = 15\nOutput: 32\nExplanation: Nodes 7, 10, and 15 are in the range [7, 15]. 7 + 10 + 15 = 32.\n
\n\n

Example 2:

\n\"\"\n
\nInput: root = [10,5,15,3,7,13,18,1,null,6], low = 6, high = 10\nOutput: 23\nExplanation: Nodes 6, 7, and 10 are in the range [6, 10]. 6 + 7 + 10 = 23.\n
