![]() ![]() If the node exists, store the value in the output string stream, and then recursively call the serialization function on its left and right child nodes.įor deserialization, we first read in the first character to generate a root node, and then recursively call the deserialization function on the left and right child nodes of the root node. ![]() įor serialization, we start from the root node. The number of nodes in the tree is in the range.You do not necessarily need to follow this format, so please be creative and come up with different approaches yourself. You just need to ensure that a binary tree can be serialized to a string and this string can be deserialized to the original tree structure.Ĭlarification: The input/output format is the same as how LeetCode serializes a binary tree. There is no restriction on how your serialization/deserialization algorithm should work. Serialization is the process of converting a data structure or object into a sequence of bits so that it can be stored in a file or memory buffer, or transmitted across a network connection link to be reconstructed later in the same or another computer environment.ĭesign an algorithm to serialize and deserialize a binary tree. ![]()
