BST — duplicate subtree
Could somebody give me a hint to the following question ?
Given balanced BST find the biggest subtree that is duplicated in that tree.
I've just came up with this problem and I don't know anything better than checking all pairs of nodes and setting them as roots. Then having those roots I can check what's the biggest duplicated subtree. Complexity will be O(n^3) . Is it possible to solve it more efficient ?
