WebJul 29, 2024 · For a size-balanced binary search tree of odd size, the root node represents the median. For a size-balanced binary search tree of even size, the approach depends on your definition of the median. In case you simply average the two central values, you would have average the root value with its neighboring value on the larger subtree's side. WebGiven the root node of a binary search tree and two integers low and high, return the sum of values of all nodes with a value in the inclusive range [low, high]. Example 1: Input: root = [10,5,15,3,7,null,18], low = 7, high = 15 Output: 32 Explanation: Nodes 7, 10, and 15 are in the range [7, 15]. 7 + 10 + 15 = 32. Example 2: billy kelly singing
