    449 - Serialize and Deserialize BST.

    Medium

    Serialization is 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.

    Design an algorithm to serialize and deserialize a binary search tree. There is no restriction on how your serialization/deserialization algorithm should work. You need to ensure that a binary search tree can be serialized to a string, and this string can be deserialized to the original tree structure.

    The encoded string should be as compact as possible.

    Example 1:

    Input: root = [2,1,3]

    Output: [2,1,3]

    Example 2:

    Input: root = []

    Output: []

    Constraints:

    • The number of nodes in the tree is in the range [0, 104].
    • 0 <= Node.val <= 104
    • The input tree is guaranteed to be a binary search tree.
