Leetcode Problem 449. Serialize and Deserialize BST
Leetcode Solutions
Postorder Traversal Serialization
- Perform a postorder traversal of the BST, appending each node's value to a string separated by spaces.
- For deserialization, split the string by spaces to get the node values in postorder.
- Use a recursive function to construct the BST by taking the last value as the root and recursively constructing the left and right subtrees.
- The left subtree consists of nodes with values less than the root, and the right subtree consists of nodes with values greater than the root.
- Continue the process until all nodes are added to the BST.
