WebObservation : In the BST all the left child nodes have a value smaller than the parent value, and also, all the right child nodes have a value greater than the parent value.; If we do an In-order traversal, we can see that the nodes in the BST are sorted in increasing order.; Approach : From the above observation, we can iteratively use the Binary Search algorithm. WebJun 2, 2011 · Given the fact were provided a Binary Search Tree, the efficient approach will be to traverse the tree and compare the root nodes absolute difference (distance) from the target while keeping track of nodes with lesser "distances" to update the closest value when we encounter a closer node to our target value. Next, we can start comparing the ...
