<prompt> Kutokana na mizizi ya Binary Search Tree BST, kurudi kiwango cha chini kabisa tofauti kati ya maadili ya nodes yoyote mbili tofauti katika mti.  <response>: To find the minimum absolute difference between any two distinct nodes in a binary search tree, you can perform an in-order traversal and compare adjacent nodes. During the traversal, you can keep track of the previously visited node initialized as null at the beginning and compare its value with the current nodes value. If the difference between these two values is smaller than the minimum difference seen so far, update the minimum difference. Heres the code in Python:class Solution: def getMinimumDifferenceself, root: TreeNode - int: self.prev None previously visited node self.min_diff floatinf initialize minimum difference as infinity def traversenode: if node: traversenode.left if self.prev is not None: self.min_diff minself.min_diff, absnode.val - self.prev.val self.prev node traversenode.right traverseroot return self.min_diffThe time complexity of this solution is ON, where N is the number of nodes in the tree, since we visit each node only once during the traversal.
