Implement a method that can serialize a binary tree and later deserialize it. Serialization turns an in-memory data structure into a bit sequence, allowing it to be saved or transmitted and then rebuilt in a different computing environment. Your approach only needs to convert a binary tree into a string from which the identical tree layout can be restored. No particular encoding or decoding scheme is required. Note: The example notation below matches the binary-tree…
