WebGiven a binary tree, efficiently create copy of it. Practice this problem. The idea very simple – recursively traverse the binary tree in a preorder fashion, and for each encountered node, create a new node with the same data and insert a mapping from the original tree node to the new node in a hash table.After creating the mapping, recursively process its children. grace cordts beaumont texas
