A subtree to be discovered as duplicate has to have at least two nodes. A single node subtree is not considered even if found having another occurrence. For example, The above tree doesn't have any duplicate nodes, though it has both the leaf nodes duplicate. (We are not considering it ...
The duplicates go in the right subtree based on the fundamental binary search tree rule. They form a chain of nodes with only right child links, as shown in Figure 8-26. One of the design choices is where to put any left child link. It should go only at the first or last duplicate...

* TreeNode(int x) : val(x), left(NULL), right(NULL) {} * };*///We can serialize each subtree. Perform a depth-first search, where the recursive function returns the serialization of the tree. At each node, record the result in a map, and analyze the map after to determine dupl...
