WebPractice this problem. The intuitive solution to clone a binary tree with random pointers is to insert each node into a a hash table. The idea is to traverse the binary tree in a preorder fashion, and for each encountered node, create a new node with the same data and create a mapping from the original node to the duplicate node in the hash table.

WebMay 17, 2024 · Its simple, as the cloned tree is exactly the copy of origninal tree. So, we can traverse both the trees parallely. As soon as we get that a_node_in_original_tree == target_node, we can directly return the address of a cloned tree (as we were also parallely traversing through the cloned tree). I hope you got the intuition. WebMar 14, 2024 · In this case, you're returning the entire copied tree once the recursion is complete. The 'new' operator is used, indicating the instantiation of a TreeNode with each visit to the various nodes of the tree during the traversal, occurring through recursive calls to 'copy', whose arguments become references to the left and right TreeNodes (if ...
