What is the lowest common ancestor in binary search tree?
Can you explain how the LCA is found in a binary search tree?
Sure. To find the LCA of two given nodes, you start from the root node of the binary search tree and traverse down the tree. If both nodes are in the left or right sub-tree of the current node, you continue to traverse down that sub-tree until their paths diverge. At that point, the current node is the LCA.
